Bipartisan congressional leaders accept Biden's church invitation for Inauguration Day
Biden, the second Catholic to be elected president, has invited the bipartisan congressional leadership to church with him on Wednesday morning ahead of his inauguration, and all parties have accepted, sources tells ABC News.
Senate Majority Leader Mitch McConnell and House Minority Leader Kevin McCarthy have separately accepted the invite and plan to attend -- a move that is sure to project unity ahead of the official transfer of power.
Senate Minority Leader Chuck Schumer and House Speaker Nancy Pelosi are also expected to attend.

She is a historic and deeply qualified choice to help lead our administration's health efforts," Biden said of Levine in a statement.

On President Trump's final full day in office, he's expected to end his term bunkered behind the White House, as he has for the last week, focused on who will benefit from his pardon powers. He is expected to issue pardons and commutations, potentially more than 100 before he departs Wednesday, but sources tell ABC News that a self-pardon and pardons for family are unlikely.
Trump is also expected to release a taped video message to the public at some point Tuesday, after first lady Melania Trump on Monday afternoon tweeted a nearly 7-minute long farewell video looking back on her time in the White House.
With just hours to go until his departure, and potentially the start of his impeachment trial pending Pelosi sending the article of impeachment to the Senate, Trump is still set to skip his successor's swearing-in -- the first president to do so since Andrew Johnson in 1869 -- and hold a large sendoff of his own hours before Biden takes the oath of office at noon on Wednesday.

Sources say Trump plans chopper via Marine One to Joint Base Andrews where he is expected to give brief remarks to supporters and departing members of his administration. Sources add that Trump has requested the event to have a "military-like feel" and will have a military band, red carpet and an honor guard. The president will then fly down to Mar-a-Lago in Florida aboard Air Force One with a small number of staffers who will be part of his post-presidency operation, according to the sources.
One of Trump's final actions as president taken Monday night was to lift travel restrictions imposed to slow the spread of the coronavirus pandemic, but in a sign of what's to come, the incoming Biden administration said the lift will be reversed before it even takes effect.
Tuesday will also see five of Biden's Cabinet nominees before Senate committees handling their confirmation hearings including Avril Haines to serve as director of national intelligence, Janet Yellen to serve as treasury secretary, Alejandro Mayorkas to serve as the homeland security secretary, Tony Blinken to serve as secretary of state, and Lloyd Austin to serve as secretary of defense. The committee schedule is ramping up at the same time Trump's impeachment trial is expected to start -- a challenge for the Senate, which is also reeling from the attack on the U.S. Capitol less than two weeks ago.
