In the wake of an assault on the Capitol Wednesday by a pro-Trump mob that led to four deaths, a growing number of Trump officials are questioning their roles in his administration, some going so far as to resign from their positions.
These are the Trump officials who have given notice so far.
Betsy DeVos: Education secretary
Betsy DeVos, U.S. secretary of education, resigned Thursday, according to a letter obtained by ABC News. Her resignation will take effect on Friday.
"We should be highlighting and celebrating your Administration's many accomplishments on behalf of the American people. Instead, we are left to clean up the mess caused by violent protestors overrunning the U.S. Capitol in an attempt to undermine the people's business," DeVos wrote in her resignation letter, addressed to President Donald Trump.
"That behavior was unconscionable for our country," she continued. "There is no mistaking the impact your rhetoric had on the situation, and it is the inflection point for me."
Elaine Chao: Transportation secretary
Elaine Chao, U.S. secretary of transportation and wife of Sen. Mitch McConnell, resigned from her role Thursday. Her resignation will take effect on Jan. 11.
"Yesterday, our country experienced a traumatic and entirely avoidable event as supporters of the President stormed the Capitol building following a rally he addressed," Chao wrote in a letter that she posted to Twitter.
"As I'm sure is the case with many of you, it has deeply troubled in me a way I simply cannot set aside," she added.
Tyler Goodspeed: Acting chairman, White House Council of Economic Advisers
Tyler Goodspeed, acting chairman of the White House Council of Economic Advisers, resigned Thursday, according to Rachael Slobodien, the council's chief of staff.

John Costello: Deputy assistant secretary for intelligence and security, Commerce Department
John Costello, the deputy assistant secretary for intelligence and security in the Commerce Department, resigned Thursday.
"I can't do it. I can't stay," he told CNBC on Thursday. "It's a nothing thing. It doesn't affect the outcome. It doesn't affect the transition. But it's what I've got, right, and it's a position I really enjoy doing. But you can't do it. And I wouldn't be surprised to see more of my friends resign over the course of the next 24 to 48 hours."
When asked if he considered himself an enabler of Trump in retrospect, Mulvaney said it was "a fair question."
Matthew Pottinger: White House deputy national security adviser
Matthew Pottinger, the White House deputy national security adviser, resigned Wednesday, according to a White House official and a person familiar with his resignation.
