House Speaker Nancy Pelosi spoke to the Chairman of the Joint Chiefs of Staff about Donald Trump’s access to the nuclear codes. In a letter to colleagues, Pelosi wrote:

“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,” Pelosi wrote. “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.”

Pelosi also said in the letter that if Trump doesn’t resign immediately, she will move to impeach Trump. The New York Times writes:

In a letter to members of the House, the speaker invoked the resignation of Richard M. Nixon amid the Watergate scandal, when Republicans prevailed upon the president to resign and avoid the ignominy of an impeachment, calling Mr. Trump’s actions a “horrific assault on our democracy.”

“Today, following the president’s dangerous and seditious acts, Republicans in Congress need to follow that example and call on Trump to depart his office — immediately,” she wrote. “If the president does not leave office imminently and willingly, the Congress will proceed with our action.”
