House Speaker Nancy Pelosi a letter to her Democratic colleagues said she reached out to the Chairman of the Joint Chiefs of Staff Mark Milley Friday morning to discuss "available precautions" for preventing Trump -- "an unstable president" -- from accessing the nuclear launch codes or initiating military hostilities before he is out of office in 12 days. She doesn't elaborate further on their discussion. 

"This morning, I spoke to the Chairman of the Joint Chiefs of Staff Mark Milley to discuss available precautions for preventing an unstable president from initiating military hostilities or accessing the launch codes and ordering a nuclear strike. The situation of this unhinged President could not be more dangerous, and we must do everything that we can to protect the American people from his unbalanced assault on our country and our democracy," she said in the letter.

Pelosi said she is also still waiting to hear back from Vice President Mike Pence as to whether or not he intends to invoke the 25th Amendment ahead of House Democrats holding a call on their options on removing Trump from office at noon.

"If the President does not leave office imminently and willingly, the Congress will proceed with our action," she wrote.

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.
