lockdown. another painful reminder of january 6. as we come on the air, president biden has ordered flags lowered to half staff in memory of slain officer billy evans. and the city has begun an all too familiar ritual: mourning the loss of a capitol police officer killed in the line of duty. there are so many questions tonight about what motivated the killer and how security around the capitol could have been breached again. we've got two reports, beginning with cbs' jeff pegues who's at the capitol. good evening, jeff. >> reporter: margaret, the barricade that that car slammed into is right there over my shoulder. also over my shoulder, heavily armed police officers are still blocking off this scene, sealing off the area as they look for evidence that may point to a motive in this attack. ( sirens ) tonight, the latest attack on the capitol stopped just steps away from the building itself. this blue four-door sedan ran

over two capitol police officers before slamming into the deployable barricade, at speeds high enough to activate the air bags. police say the driver got out with a knife and then attacked officers on the scene, stabbing one in the face. >> the suspect exited the vehicle with a knife in hand. our officers then engaged that suspect. he did not respond to verbal commands. the suspect did start lunging toward u.s. capitol police officers, at which time u.s. capitol police officers fired upon the suspect. >> reporter: that suspect, 25- year-old noah green, originally from indiana, is dead. and so is one of the police officers, identified this afternoon as william evans, an 18-year veteran of the force, who was memorialized this afternoon by a procession through the streets. another officer is in stable condition at george washington university hospital.

police and national guard swarm the area after the incident unfolded looking for other suspects. a park police helicopter was seen landing on capitol grounds. green is now believed to be the only attacker. >> it does not appear to be terrorism related but, obviously, we'll continue to investigate. >> reporter: the shooting happened on constitution avenue, one block from the capitol. the area had been locked down for most of the last three months following the january 6 assault. the large security perimeter was scaled back in just the last few weeks. the capitol police were highly criticized for their lax preparation and for not heeding intelligence warnings ahead of the january attack. one officer died following the assault, and one other died by suicide. today, acting police chief yogananda pittman became emotional when addressing how difficult this year has been for the force. >> this has been an extremely

difficult time for u.s. capitol police, so i ask that you keep our u.s. capitol police family in your thoughts and prayers. >> reporter: president biden says that he is being briefed on the incident by his homeland security advisor. he also expresses his gratitude to the capitol police, as well as the national guard, for their quick response, and he ordered the flags at the white house to be lowered to half staff. margaret. >> brennan: jeff pegues, thank you very much. tonight, investigators are working to piece together a profile of noah green, focusing on what that 25-year-old suspect left inside the blue nissan he smashed into the barricade, and smashed into the on the clues he left online. here's cbs' catherine herridge. >> reporter: sources tell cbs news law enforcement is poring through social media accounts linked to 25-year-old noah green looking for a motive and tracking his movements prior to

the attack. based on social media posts, it appears green hit a low point in mid march writing he has been tried with some of the biggest imaginable tests in his life and was unemployed. shortly after the attack, u.s. capitol police said the suspect was not on their radar. >> we do not have the suspect on file with u.s. capitol police, so there's no indication at this time that there is any nexus to any member of congress. >> reporter: green's social media activity suggests he posted about louis farrakhan and the nation of islam and at one point encouraged his followers to study revelations, study the signs of end times, study who the beast is, study who the antichrist is. tonight, there is no evidence the suspect had any accomplices. law enforcement will continue to drill down on his social media, his travel records, and his phone, searching for an explanation for why this young man launched an attack against police here at the capitol. margaret.

>> brennan: a developing story. thank you, catherine. well, there is new guidance tonight from the c.d.c., dramatically easing travel recommendations for those who have been fully vaccinated, but it comes at the same time that the country is seeing a surge of covid infections, especially among young people. here's cbs' omar villafranca. >> reporter: with 58 million now fully vaccinated, the c.d.c. has news many have been waiting for. >> fully vaccinated people can resume travel at low risk to themselves. >> reporter: vaccinated americans won't have to get tested or quarantined after travel, but the guidance comes with a warning. >> c.d.c. is not recommending travel at this time due to the rising number of cases. >> reporter: nationwide, cases rising at least 10% in 24 states, michigan the hardest hit. daily cases up five fold since the end of february. the biggest spike in kids, as

infection rates jump 230% in those under ten. johnson & johnson now expanding trials on children as young as 12, coming on the heels of pfizer saying it is 100% effective on adolescents. moderna tonight getting permission from the f.d.a. is going to increase doses in each vial from 10 to 15 which could help speed up distribution and northwestern medicine releasing the study showing that pregnant women vaccinated early in the third trimester were likely to pass on antibodies to their newborns, a potentially significant finding to expectant mothers concerned about getting the vaccine. as states continue to relax restrictions, michigan's governor is hoping vaccines are the way out. >> we may be seeing the light at the end of the tunnel, but we are still in the tunnel, and it bears repeating, the best thing that we can do right now is to follow the protocols. >> reporter: this vaccination site in los angeles has administered about 300,000 doses in six weeks.

nationwide, expect to see more pharmacies to offer more doses as the u.s. government plans to double the amount of pharmacies receiving the vaccine. margaret. >> brennan: omar villafranca in los angeles. now to minneapolis, an emotional week at the murder trial of derek chauvin. it ended with a veteran lieutenant telling the jury that it was totally unnecessary for the former police officer to kneel on george floyd's neck. cbs' jamie yuccas is following the trial. >> if your knee is on a person's neck, that can kill him. >> reporter: tonight, damning testimony from the most senior minneapolis police officer, lieutenant richard zimmerman, a 35 year veteran with the department, highly critical of derek chauvin's use of force on george floyd. >> totally unnecessary. >> what do you mean? >> pulling him down to the ground, face down, and putting your knee on the neck for that amount of time is just uncalled for.

>> is he breathing right now? check his pulse! >> i saw no reason why the officers felt they were in danger. >> in your opinion, should that restraint have stopped once he was handcuffed and prone on the ground? >> absolutely. >> reporter: the defense immediately questioned zimmerman's qualifications to make those judgments, pointing out he hasn't had to patrol a beat since 1993. >> the frequency with which you have to use higher levels of force as an investigator doesn't happen all that often, right? >> correct. >> and it would not be within your normal role or job duties to do such a use of force analysis, right? >> that's correct. >> yeah, i was just going to call you. >> reporter: in this video we hear from chauvin himself, justifying his actions while on a call with his supervisor shortly after floyd was taken away in an ambulance. >> we just had to, had to hold the guy down.

he was-- was going crazy. >> reporter: it's been a very emotional week for the prosecution witnesses, many of them weeping on the stand, expressing feelings of helplessness and guilt. do you feel that the prosecution at this point has the upper hand in the case? >> the prosecution has the burden of proof beyond a reasonable doubt and they have gone a long way to satisfy this burden. they should reassess over the weekend how much more they need. >> reporter: now, the defense has been suggesting chauvin's knee was on floyd's shoulder, not his neck. when questioned by chauvin's attorney, lieutenant zimmerman said that the shoulder is used in training when handcuffing a suspect. margaret. >> brennan: jamie yuccas on the scene in minneapolis. tonight, major league baseball announced it is moving this july's all-star game out of atlanta. the change comes in protest to a new georgia law overhauling how

state elections are run and restricting voting by mail. m.l.b. commissioner rob manfred says baseball supports voting rights for all americans. in a statement, georgia governor brian kemp said baseball "caved to fear, political opportunism and liberal lies." there are disturbing new allegations tonight against florida republican congressman matt gaetz as he faces a federal sex trafficking investigation. we get details now from cbs' major garrett. >> reporter: the investigation into matt gaetz, a staunch ally of former president trump, is growing tonight, now involving several offices of the justice department, a top aide to the congressman resigning as the scandal widens. at issue is gaetz's relationship with a 17-year-old girl. gaetz could face federal charges if he traveled across state lines or provided anything of value-- airline tickets, meals hotel rooms-- in exchange for sex with her, something he has denied.

>> it is a horrible allegation and it is a lie. >> reporter: gaetz could also face state charges of prostitution. "the new york times" reported obtaining receipts suggesting gaetz and an associate joel greenberg paid for sex after using web sites to locate potential partners. greenberg was indicted last year on sex trafficking charges. gaetz's congressional office said "matt gaetz has never paid for sex, matt gaetz has never been on any such web sites whatsoever." >> categorical denials are all about a political career right now. >> reporter: scott fredericksen is a former federal prosecutor. >> prosecutors don't pay a lot of attention to that. they pay attention to, do they have the witnesses to support their allegations. >> reporter: "the new york times" spoke to people familiar with the sexual encounters and two said the drug ecstasy was involved. gaetz recently became engaged. as news worsened for him this week, radio silence from fellow republicans. gaetz has not been charged of a crime. at this stage, he is a subject, not the target, of this wide

ranging federal investigation. >> brennan: major garrett, thank you. there's much more news ahead on tonight's "cbs evening news." new details on what caused a deadly train wreck in taiwan. and the remarkable rescue of a little girl alone on top of a mountain. wait until you hear how she was spototted. ththinkorswim m trading. from td d ameritradede. gillette p proglid . five blalades and a a pivotig flexbaba l ththinkorswim m trading. designeded to get vivirtu lly every hahair on the e first str

in keeping the faith. here's steve hartman with tonight's "on the road." >> reporter: at the start of the pandemic, father tim pelc of saint ambrose catholic church near detroit had a problem: how in heaven's name was he going to sprinkle holy water on people's easter baskets while maintaining social distance? as you're pouring the holy water into the water pistol, are you saying, "forgive me lord?" >> yes, it's a form of absolution. i won't go through that. >> reporter: the pictures went viral last year, much to the delight of most people. >> i know i had a couple of detractors in the clergy saying that this was sacrilegious to do it that way and i said, "guys, we're talking about chocolate bunnies and sausages here." >> reporter: that's why this year he plans to go bigger. >> no. >> reporter: not a bigger squirt gun, just more easter baskets. t and it's that kind of ingenuity we've seen across the country

throughout the pandemic, from choir in your car... >> let my people go. >> reporter: ...to zoom passover seders. >> no, i will not let them go. >> reporter: we saw people bundled up in beach chairs and lots of praying behind the wheel. the drive-through has been a real godsend to folks of all faiths. but even those who stayed home found ways to keep it special, like 82-year-old laverne wimberly of tulsa, oklahoma, who still got dressed up to the nines every sunday, always in a different outfit, just to watch her service on the computer. >> it's kind of a reverence. you want to be respectful when you go to church and primarily that's the reason why i continue. >> reporter: you have all these clothes and i see not one outfit is hanging up on the treadmill. >> absolutely not. >> reporter: but laverne says she is running out of closet space. >> that's right, it cannot go another 52 sundays, that's for sure. ( laughs ) ( singing ) >> reporter: fortunately, there is much more hope this easter

weekend compared to last. thanks to the vaccines, the renewal we celebrate in all our spring traditions feels especially profound. i felt that firsthand when my wife's parents, now both fully vaccinated, came to visit us this week. >> look at you! >> reporter: it was the first time we had seen them in over a year. >> i love you. >> i love you, too! >> reporter: there's an easter miracle we can all believe in. steve hartman, cbs news, "on the road" at home. >> brennan: we'll be right back. we love our new home. there's so much space. we have a guestroom now. but we have aunts. you're s slouching a again, t. expipired. expirired. expire. thanks, , aunt bonninie.
