U.S. President Donald Trump said in a tweet on Friday he has named Homeland Security Secretary John Kelly as White House chief of staff, replacing Reince Priebus.

“I am pleased to inform you that I have just named General/Secretary John F Kelly as White House Chief of Staff. He is a Great American….,” Trump said on Twitter.

More to come.
