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.

These actions threaten our democracy and our Republic. Trump is entirely unfit to remain in office, and needs to go,” he tweeted on Wednesday.
