White House deputy chief of staff Daniel Walsh will leave the Trump administration, the White House confirmed Monday.

Walsh was responsible for planning foreign trips for the administration as well as making decisions on White House aides’ use of government resources. He was one of the few current White House officials who had been present since Trump’s inauguration and had been a government employee for nearly three decades, according to The Washington Post.

“Dan Walsh is a fantastic member of the team, and has served the White House and my Administration with the utmost professionalism and honor,” Trump said in a statement to The Washington Post. “He has accepted a great job in the private sector, as almost all of my people who develop experience in the White House have done.”
