Capitol Attack Leads Democrats to Demand That Trump Leave Office

The vice president, who for four years had remained loyal to Mr. Trump to the point of obsequiousness, was angry in return at the president’s public lashing. Senator James M. Inhofe, Republican of Oklahoma, told The Tulsa World that Mr. Pence privately expressed a sense of betrayal by Mr. Trump “after all the things I’ve done for him.”

Even when the vice president had to be evacuated during the siege on Wednesday, the president never checked with him personally to make sure he was OK. The Secret Service agents wanted the vice president to leave the building, but he refused and sheltered in the basement, according to two officials. Congressional leaders were whisked to Fort McNair for their safety, but the vice president later urged them to finish the count at the Capitol.

On Thursday, Mr. Pence did not go to the White House complex, instead working out of the vice-presidential residence, according to administration officials.

He was not the only one feeling betrayed by the president. In the White House, aides were exasperated and despondent, convinced that Mr. Trump had effectively nullified four years of work and ensured that his presidency would be defined in history by the image of him sending a mob to the Capitol in an assault on democracy.

Ms. Chao stepped down a day after her husband, Senator Mitch McConnell of Kentucky, the Republican leader, forcefully repudiated Mr. Trump’s effort to overturn the election. “Yesterday, our country experienced a traumatic and entirely avoidable event as supporters of the president stormed the Capitol building following a rally he addressed,” she wrote in her resignation letter. “As I’m sure is the case with many of you, it has deeply troubled me in a way that I simply cannot set aside.”

In her own letter, Ms. DeVos laid the responsibility for the mayhem directly at Mr. Trump’s feet. “There is no mistaking the impact your rhetoric had on the situation, and it is the inflection point for me,” she wrote, just a couple weeks after Mr. Trump pardoned four security contractors convicted of war crimes in Iraq committed while working for her brother, Erik Prince.
