Trump announces new impeachment legal team

White House Press Secretary Jen Psaki confirmed Friday that Biden is planning to launch a task force dedicated to migrant family reunification on Tuesday, which will be led by incoming Department of Homeland Security Secretary Alejandro Mayorkas. 

Psaki blamed the delay of Biden’s planned immigration actions from late this week to early next week on Senate Republicans’ efforts to block Mayorkas’s confirmation.

“We had planned to do it this week because we had hoped that Ali Mayorkas would be confirmed by the end of this, but because of the filibuster of his nomination, we expect him to be confirmed on Monday evening and the president will sign it on Tuesday and then secretary Mayorkas will be overseeing that moving forward,” Psaki said during her press briefing Friday. 

In addition, Psaki confirmed reports that First Lady Jill Biden will be personally involved in the family reunification efforts.

White House Press Secretary Jen Psaki shared Biden’s reaction to headlines this morning that Johnson & Johnson said its vaccine is 85% effective against severe COVID-19 disease.

“The president is encouraged by positive data on a potential new vaccine,” Psaki said. "He also knows that this is just new data and now is the time for the FDA to do its job of evaluating the safety and efficacy of the vaccine."

In the wide-ranging briefing, Psaki also took multiple questions about the controversy surrounding GameStop stock that upended Wall Street and drew swift reactions from lawmakers this week. 

“I know the SEC issued a new statement earlier this morning,” she said. “I’d certainly point you to that and others to that.” 

“We of course respect the role of regulatory agencies, they are closely monitoring the situation, but it’s under their purview at this point in time,” she added. 

Psaki distanced the White House from the saga, adding, that “part of our education can be conveying to people that the SEC is the regulatory body that would oversee this and can speak to it further.”

President Joe Biden ends a busy week with a visit to wounded service members at Walter Reed National Military Medical Center on Friday. 

The afternoon visit will also mark the first time the new president will ride Marine One, and it's unclear whether he will stop to take questions from reporters the way his predecessor did before boarding the chopper on the White House South Lawn. 

Earlier Friday, Biden and Kamala Harris will receive the President’s Daily Brief at the Oval Office as well as an economic briefing with the new Treasury Secretary Janet Yellen. 

Biden is not expected to sign any new executive orders Friday, though he has been churning them out since he entered office. 

Meanwhile, White House press secretary Jen Psaki will hold a briefing this morning at 10 a.m. ET.

Florida Rep. Matt Gaetz on Thursday traveled to House Republican Conference Chair Liz Cheney's home turf to urge Wyomingites to vote her out of office in 2022, arguing that the at-large congresswoman is part of the "establishment power brokers" in Washington and out of touch with the people she represents.

In an interview with ABC News Live Prime following the rally, anchor Linsey Davis pressed Gaetz on how his rally will help his party win back the House, Senate and White House in the next two cycles.

"I want Republicans to win, but to do that, we have to be worthy of winning," Gaetz argued. "Right now, there's an identity crisis in the Republican Party. There are some in Washington who believe that we've got to purge Trumpism ... I think a different view. I think that we've got to get out in the country, and we have to marshal a positive populism that will lead to better candidates, better policies and ultimately a better electoral performance."
