After tweeting the president must go, citing the insurrection at the Capitol, Gabriel Noronha was fired from the State Department on Thursday, he has confirmed.

Noronha, who served as a senior adviser and spokesperson for Iran policy, is the first Trump administration official fired for speaking out against the president over the week’s events.

“President Trump fomented an insurrectionist mob that attacked the Capitol today. He continues to take every opportunity to obstruct the peaceful transfer of power. These actions threaten our democracy and our Republic. Trump is entirely unfit to remain in office, and needs to go,” he tweeted on Wednesday.

Biden is pressing forward with his inauguration on Jan. 20 -- and Trump won't be there, the president announced in a tweet Friday morning.

After Trump tweeted he wouldn’t attend, Vice President Mike Pence’s press secretary, Devin O’Malley, told ABC News, “Vice President Pence and the Second Lady have yet to make a decision regarding their attendance."

Earlier Friday, Trump took to Twitter to call his supporters "American Patriots" who "will have a GIANT VOICE long into the future" and "not be disrespected or treated unfairly in any way, shape or form!!!

The tweets come hours after Trump, for the first time, said he would focus on an "ensuring a smooth, orderly and seamless transition of power." In the video posted Thursday evening, he also rebuked those who vandalized the Capitol.

"To those who engaged in the acts of violence and destruction, you do not represent our country. And to those who broke the law, you will pay," Trump said.

While Democrats are looking at options for removing Trump from office, Biden has so far declined to comment on his stance for impeaching Trump or invoking the 25th Amendment with a spokesperson for his transition team saying Thursday he and Vice President-elect Kamala Harris are focusing on their duties.

Meanwhile, Trump has suggested to advisers that he wants to grant himself a pardon before leaving office, sources familiar with the discussions told ABC News.

Keeping on message, Biden is pressing forward with his transition and is expected to announce more picks for his economic and jobs team Friday afternoon including Rhode Island Gov. Gina Raimondo as his choice for secretary of commerce and Boston Mayor Marty Walsh as his pick to serve as his secretary of labor. Walsh would be the first union member to serve in the role in almost half a century. Biden also named Isabel Guzman as his pick for small business administrator and Don Graves as his choice for secretary of commerce.

Biden and Vice President-elect Kamala Harris have announced 21 additional members of the White House National Security Council including Yohannes Abraham as the chief of staff and executive secretary and Emily Horne as a senior director for press and NSC spokesperson.

The vast majority of the nominees previously served under the Obama administration. The positions do not require Senate confirmation.

Trump has announced he will not attend Biden's inauguration on Jan. 20.

"To all of those who have asked, I will not be going to the Inauguration on January 20th," Trump tweeted Friday morning.

It comes just hours after Trump, in video posted to Twitter Thursday evening, effectively conceded and said he would focus on an "ensuring a smooth, orderly and seamless transition of power."

Only incumbent presidents -- John Adams in 1801, John Quincy Adams in 1829 and Andrew Johnson in 1869 -- did not attend the inaugurations of their successors. Johnson, like Trump, was impeached and not convicted.

House Speaker Nancy Pelosi, in a new letter to Democrats on Saturday, asked members to prepare to return to Washington this week -- another signal that the House could take up and pass the impeachment article to the Senate after it is formally introduced on Monday.

Pelosi thanked fellow Democratic representatives for speaking with her on a conference call Friday and said she was taking their considerations into account. She did not specifically mention voting on impeachment in the letter, though.

"Since that call, I have received scores of communications from Members expressing your views about how we go forward and regarding a strong presence of our Caucus in the Capitol," she wrote. "Over the last few days, I have discussed your views with Constitutional lawyers, both inside and outside the Congress, to consider the parliamentary and constitutional options available to us."

"From what I have heard from Members, and from the deluge that I have received from the public, it is clear that, once again, the Times Have Found Us to save our democracy," Pelosi added in the letter. "We will be proceeding with meetings with Members and Constitutional experts and others. I continue to welcome your comments. I urge you to be prepared to return to Washington this week."

While Democrats are hopeful Republicans will back their effort, none have come out and said they would back the charge as drafted.

Pelosi said at a press conference on Thursday, "If the Vice President and Cabinet do not act [on the 25th Amendment], the Congress may be prepared to move forward with impeachment."

Some Democrats planned to connect with Republican colleagues this weekend to gauge their support and encourage them to back the effort.
