Former Vice President Joe Biden knew his fellow 2020 Democratic presidential candidates would focus on him during last week's debate, but he had no idea the charge would be led by Sen. Kamala Harris (D-Calif.), Biden told CNN's Chris Cuomo in an interview that aired Friday morning.

"I was prepared for them to come after me, but I wasn't prepared for the person coming at me the way she came at me," he said. Biden told Cuomo one reason why he felt that way is because he knows Harris, and she also knew his late son, Beau Biden. Harris brought up race and busing to desegregate schools in the 1970s; at the time, Biden opposed this, arguing that the practice did not offer students equal opportunities.

Biden told Cuomo Harris mischaracterized his position, and while he did not think the Department of Education should mandate busing, local districts needed to do what they saw fit. At the time, he received an "overwhelming response from the African American community" in Delaware, he said, and "they did not support it." Today, there's still the need to "equalize education in every area," Biden said. "Every child out there is capable, but they're living in circumstances that make it difficult. So what are we doing? We're sitting around here as if it's an insoluble problem."

Harris and other candidates also criticized Biden for saying he was able to work with two segregationist senators in the 1970s, and Biden said he thinks they should be focusing on the future rather than what happened decades ago. "I get all this information about other people's past and what they've done and not done," he said. "And, you know, I am just not going to go there. ... We should be debating what we do from here."

U.K. Prime Minister Boris Johnson said Friday that there's "some evidence" a surging COVID-19 variant may be more deadly than the original strain.

The B117 strain was first identified in London, and has since spread across the U.K. and arrived in other U.S. and other countries. "In addition to spreading more quickly, it also now appears that there is some evidence that the new variant ... may be associated with a higher degree of mortality," Johnson said in a Friday press conference.

Before Johnson's announcement, evidence suggested the variant was no more inherently deadly than the original COVID-19 strain. But evidence the U.K.'s New and Emerging Respiratory Virus Threats Advisory Group assessed for the government shows that it could be up to 30 percent more deadly. Sir Patrick Vallance, the government's chief scientific advisor, cautioned that the data is "not yet strong," saying "there's a lot of uncertainty around these numbers and we need more work to get a precise handle on it."

Even if the variant is not necessarily more deadly, its rapid transmission rate could allow it to infect — and therefore kill — more people. Still, research suggests both major COVID-19 vaccines currently in distribution will still be just as effective against the new strain. Kathryn Krawczyk

Former President Donald Trump’s second impeachment trial appears on track to begin within days, with an article of impeachment against him headed to the Senate.

Senate Majority Leader Chuck Schumer (D-N.Y.) announced Friday that House Speaker Nancy Pelosi (D-Calif.) plans to transmit an article of impeachment charging Trump with incitement of insurrection to the Senate on Monday. Pelosi later confirmed this timing.

"Make no mistake: a trial will be held in the United States Senate, and there will be a vote on whether to convict," Schumer said.

Senate Minority Leader Mitch McConnell (R-Ky.) has suggested the trial should be delayed until the middle of February, adding that Trump deserves a "full and fair process where the former president can mount a defense," NBC News reports. But Axios notes that "the Senate is required to begin the impeachment trial at 1 p.m. the day after the article is transmitted." The trial would, therefore, be set to begin on Tuesday, Jan. 26, though as Politico writes, this is assuming Schumer and McConnell don't "agree to a different timetable" before then.

The House impeached Trump again for "incitement of insurrection" after a mob of his supporters stormed the Capitol building in a deadly riot. His forthcoming second impeachment trial will be the first to ever take place against a former president. Brendan Morrow

Some members of the National Guard stationed near the Capitol after Inauguration Day were forced to use a parking garage for a rest area last night, and it's unclear who is to blame.

Politico first reported that the soldiers were pushed out from the Capitol and congressional office buildings Thursday night, with one Guard member saying they were told to set up new command centers outside or in hotels. Breaks after Guard members completed their 12-hour shifts were supposed to be taken outside or in a nearby parking garage, another member said. Photos soon showed dozens of troops huddled in the garage.

The incident prompted outrage and finger pointing from both lawmakers on sides of the aisle. House Minority Leader Kevin McCarthy (R-Calif.) made House Speaker Nancy Pelosi (D-Calif.) and Senate Majority Leader Chuck Schumer (D-N.Y.) his scapegoats, while Schumer promised he would "get to the bottom of this." By Friday morning, the troops were allowed back into the Capitol.

Sen. Tammy Duckworth (D-Ill.) implied in a Thursday tweet that the Capitol Police were the ones who'd ordered the Guard out of the Capitol, and the D.C. National Guard confirmed to Military Times in a statement that the police had made the call. But two soldiers told Military Times that the police shouldn't be blamed. "I hate that senators are blaming this on the Capitol Police,” one said, recounting how the force has done "nothing but act like coworkers to us." Another Guard soldier said it's the senators who "keep increasing the Guard force and decreasing the space we are allowed to rest in."

State governors are the commanders in chief of their individual Guard forces. Florida Gov. Ron DeSantis (R) ordered his Guard members home Friday morning after the incident. Kathryn Krawczyk

Hall of Fame slugger Hank Aaron — thought by many to be Major League Baseball's "legitimate" home-run king — has died at 86, his daughter said on Friday. Aaron, who played from 1954 to 1976, mostly with the Milwaukee and Atlanta Braves, finished his career with 755 home runs — a record that stood until 2006, when he was surpassed by the steroid-assisted Barry Bonds.

Aaron still holds major-league records for RBI, extra-base hits, and total bases, and won his lone MVP award in leading Milwaukee to the 1957 World Series title. But Aaron is also revered for his fortitude in facing down racism as he chased Babe Ruth's career home run record in the early 1970's. "When people finally realized I was climbing up Ruth's back, the 'Dear N----r' letters started showing up with alarming regularity," he wrote in his 1991 memoir. "There's no way to measure the effect those letters had on me, but I like to think every one of them added another home run to my total." The Associated Press reports Aaron died peacefully in his sleep. Jacob Lambert

Vaccinated health care workers are headed to next month's Super Bowl.

The National Football League said Friday it will allow a total of 22,000 fans to attend Super Bowl LV, which will be held at Raymond James Stadium in Tampa, Florida, CNN reports. The league said it made this decision following "discussions with public health officials, including the CDC, the Florida Department of Health, and area hospitals and health care systems."

Approximately 7,500 health care workers who have received their COVID-19 vaccine are scoring free tickets to the game from the NFL. The league posted a video Friday showing NFL commissioner Roger Goodell sharing the news with one group of health care workers.

"We can't thank you enough, and we hope this program will be a small way to celebrate you, honor you, and most importantly, thank you," Goodell says in the video.

The NFL says health officials have "reviewed and provided feedback on the NFL's comprehensive plans that will enable the league to host fans and the vaccinated health care workers in a safe and responsible way," and it plans to "enhance the already rigorous COVID-19 protocols" it has been using, including mandating mask-wearing. The Raymond James Stadium "has a capacity of around 65,000," the "plan is that for each pod of non-vaccinated fans, a group of vaccinated health care workers would be seated in the row behind, staggered to the side, throughout the stadium," The Washington Post writes.

Super Bowl LV is scheduled for Feb. 7. Brendan Morrow

House Republican Conference Chair Liz Cheney is facing an internal resistance after splitting from her party on former President Donald Trump's impeachment.

Cheney, the No. 3 Republican in the House, was one of only a handful of Republicans who voted to impeach Trump over his role in inciting the Capitol riot. More than a majority of GOP House members have since indicated they'd support ousting Cheney from her leadership spot, while at least two other Republicans have lined up to replace her, Politico reports.

At least 107 House members — more than half the caucus — privately support removing Cheney from power, multiple GOP sources involved in the effort told Politico. Meanwhile New York Reps. Elise Stefanik and Lee Zeldin, who defended Trump during both of his impeachments, are reportedly looking to replace her.

House Minority Leader Kevin McCarthy (R-Calif.) and Minority Whip Steve Scalise (R-La.) have said they don't intend to remove Cheney. But McCarthy also echoed Republicans' reported anger that Cheney voiced her support of impeachment the day before the House vote, giving Democrats time to use her views in their own arguments. "Questions need to be answered," such as the "style in which things were delivered," McCarthy told reporters Thursday.

Many other Republicans, including some who voted against impeachment, meanwhile don't want Cheney removed just for "vot[ing] her conscience," as Rep. Michael McCaul (R-Texas) put it. Others argue removing Cheney would fly in the face of the party's unification message in the post-Trump era — something Cheney herself is trying to counter by making "making calls to all corners of the conference to hear lawmakers out," Politico reports.
