President Joe Biden is again undoing actions undertaken by the Trump administration. In a letter to House Speaker Nancy Pelosi Sunday, Biden announced he was withdrawing 73 proposed rescissions previously sent to Congress by former President Donald Trump on Jan. 14. 

The action would unfreeze $27.4 billion in cuts to previously approved funding for government programming.

"The withdrawals are for the Departments of Agriculture, Commerce, Education, Energy, Health and Human Services, Homeland Security, the Interior, Justice, Labor, State, and the Treasury, as well as the African Development Foundation, the Commission of Fine Arts, the Corporation for National and Community Service, the District of Columbia, the Environmental Protection Agency, the Inter-American Foundation, the Millennium Challenge Corporation, the National Endowments for the Arts and Humanities, the National Gallery of Art, the Peace Corps, the Presidio Trust, the United States Agency for International Development, the United States Army Corps of Engineers, the Woodrow Wilson International Center for Scholars, and the Legislative Branch," according to a statement from the Biden administration.

A day after all five of former President Donald Trump's impeachment legal team quit, a new team has been selected.

Trial lawyers David Schoen and Bruce L. Castor, Jr. will lead his impeachment defense team, according to a statement from Trump Sunday.

“It is an honor to represent the 45th President, Donald J. Trump, and the United States Constitution,” Schoen said in a statement.

“I consider it a privilege to represent the 45th President. The strength of our Constitution is about to be tested like never before in our history. It is strong and resilient," Castor added. "A document written for the ages, and it will triumph over partisanship yet again, and always.”

Trump's former team, which was led by South Carolina lawyer Butch Bowers, resigned in part because of disagreements over how to mount Trump’s defense, sources told ABC News. The lawyers had planned to argue the constitutionality of holding a trial given Trump is now a former president.

The Senate trial is scheduled to begin on the week of Feb. 8.

Unity was the focus of Biden's campaign, but absent gaining even one Republican vote for his coronavirus relief package, what does that mean going forward, ABC's "This Week" Co-anchor Martha Raddatz asked Senior White House Correspondent Cecilia Vega.

"It's something we've heard almost every day since he's been in office for the last few days. He said that there would be this epiphany by Republicans if Donald Trump left. He also, on a conference call, told supporters at one point that he would -- could end up eating his words but that he believed Republicans essentially would come around," Vega said Sunday. "Martha, we may end up seeing the president eating his words on this."

"The Biden team is at a crossroads right now. They've got to decide whether it is bipartisanship and unity that prevails or whether they're going to potentially go at it alone and just forego this effort of unity," Vega continued. "It is looking more and more like they're going to end up going at it alone."

Ohio's Sen. Rob Portman's decision to retire opened a major new battleground in the fight for Senate control in 2022. But after former President Donald Trump easily carried the buckeye state last November, do Democrats have a shot at flipping the seat?

FiveThirtyEight's Nate Silver gave ABC's "This Week" an early forecast.

"Democrats have a chance, it's just not a very good chance … it probably depends on the GOP having a really weak candidate or Democrats, a very strong one," he said Sunday.

It's a visit that carries importance that's both substantive and symbolic.

House Minority Leader Kevin McCarthy is expected to meet with former President Donald Trump on Thursday at Mar-a-Lago. The top House Republican and potential future speaker of the House is visiting the  twice-impeached and  still-to-stand-trial former president, just eight days after he left Washington before his successor was sworn in.

Things are breaking Trump's way -- despite or even because of the turmoil inside the Republican Party. State parties and activists are  lining up behind him, prospects for  impeachment conviction are fading fast and Biden's executive orders and progressive priorities are making it easier for the GOP to find unified messaging.

Perhaps most tellingly, intra-party fights appear riskier for those  who stand against him than those who remain loyal -- at least for the moment. McCarthy's visit comes as efforts move forward to oust the No. 3 House Republican, Rep. Liz Cheney, over her support for impeachment; McCarthy is in Florida, yet Florida Republican Rep. Matt Gaetz, a Trump loyalist, will be in Cheney's Wyoming on Thursday.

Republicans have a whole lot of work to do to figure out what the party needs to look like from here. But the fact that Trump is having some decent political breaks, even while mostly silent and under impeachment, says more than the tweets the former president can't send.
