In the wake of a riot at the U.S. Capitol yesterday, Donald Trump has lost his first cabinet secretary.

Elaine Chao is stepping down as the secretary of transportation after remaining in this position for four years.

"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 said in a statement.

"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."

Chao is married to Senate Majority Leader Mitch McConnell.

Chao's resignation takes effect on January 11.

She will be succeeded by Pete Buttigieg after the Biden administration takes over on January 20, pending Buttigieg's confirmation by the U.S. Senate.

Over Twitter, some are criticizing Chao for not sticking around to try to invoke the 25th amendment of the U.S. constitution, which would remove Trump as president.

Section 4 of the 25th amendment allows for the vice president to assume the powers and duties of the president if a majority of cabinet secretaries agree that Trump is unfit for office.
