First pardoned Jan. 6 rioters released in DC

The Bidens boarded a government plane to leave Washington and head to Santa Ynez, California, following Trump’s inauguration.

"We're leaving office -- we're not leaving the fight," Biden said in his remarks to staffers at Joint Base Andrews before boarding.

"I've been doing this for 50 years, you’re the best group of people," Biden said. "It's been the honor of my life to serve as your president."

Biden departed as Trump continued to speak to his supporters at Emancipation Hall.

After promising 'unity' in his inaugural address, Trump is reverting back to bulldozing political opponents like Nancy Pelosi and Liz Cheney.

"She's guilty as hell," he said of Pelosi over her response to the attack on the U.S. Capitol -- where he was speaking -- by a pro-Trump mob.

He called Liz Cheney, a Republican who endorsed Kamala Harris over Trump because of his actions after the 2020 election, a "disaster."

"She's a crying lunatic and crying, crying Adam Kinzinger, he's a super crier," Trump said.

Within minutes of Trump’s swearing-in, a handful of lawsuits were filed against the Trump administration targeting the controversial Department of Government Efficiency, or DOGE, and its leader, tech billionaire Elon Musk.

The litigation accuses the Trump administration of skirting federal transparency rules that require advisory groups like DOGE to disclose its hiring practices and interactions with government bodies, while a fourth suit seeks records regarding DOGE’s interactions with the Trump transition team.

In more off-the-cuff remarks inside the Capitol's Emancipation Hall after his address, Trump spoke about people who have been convicted for their roles in the Jan. 6 attack on the Capitol as "hostages."

"I was going to talk about the J6 hostages," Trump said. "But you'll be happy because, you know, it's action not words that count."

Trump previously promised to pardon some Jan. 6 rioters on Day 1.

He also went after former Reps. Liz Cheney and Adam Kinzinger, two Republican members of the House Jan. 6 Committee who are outspoken critics of Trump because of his actions after the 2020 election.

"And I was going to talk about the things that Joe did today with the pardons of people that were, very, very guilty of very bad crimes, like the Unselect Committee of political thugs," Trump said.
