Chad Wolf leaves his post as Acting Secretary of Homeland Security (DHS). FEMA Administrator Pete Gaynor takes over the position.

Wolf publicly condemned the mob riots on the Capitol last week. Hours later news broke that the White House pulled his nomination to be permanent DHS Secretary, though a spokesperson said it was not related.
The letter message Wolf sent out says his decision is “warranted by recent events, including the ongoing and meritless court rulings regarding the validity of my authority as Acting Secretary.”
