President Trump’s homeland security adviser Tom Bossert has resigned at the request of new national security adviser John Bolton, a report said Tuesday.

Bolton, who joined the White House on Monday as the replacement for H.R. McMaster, pushed Bossert out, Bloomberg reported.

Bossert, 43, who has been with the Trump administration since the inauguration, was Trump’s point man on the hurricanes that struck Texas, Florida and Puerto Rico.

The White House announced he was stepping down on Tuesday.

“The President is grateful for Tom’s commitment to the safety and security of our great country. Tom led the White House’s efforts to protect the homeland from terrorist threats, strengthen our cyber defenses, and respond to an unprecedented series of natural disasters,” White House press secretary Sarah Huckabee Sanders said in a statement. “President Trump thanks him for his patriotic service and wishes him well.”

His departure follows that of Michael Anton, the spokesman for the National Security Council, who announced his decision to step down on Sunday.
