The US president appointed U.S. Ambassador to Germany Richard Grenell as acting director of national intelligence.
"I am pleased to announce that our highly respected Ambassador to Germany, @RichardGrenell, will become the Acting Director of National Intelligence," Trump said on Twitter.
"Rick has represented our Country exceedingly well and I look forward to working with him. I would like to thank Joe Maguire....for the wonderful job he has done, and we look forward to working with him closely, perhaps in another capacity within the Administration!" he wrote.
Maguire has served in the role since August after taking over the acting post on Aug. 15, when Dan Coats stepped down.
Trump's pick for the permanent job is subject to confirmation by the Senate.
