After making the announcement, President Trump left the White House for Joint Base Andrews, where he boarded Air Force One for a trip to Montana for a campaign style rally.
Veteran Fox News executive Bill Shine is President Trump's new right-hand-man for White House communications.
Shine stepped down at Fox News past year after he was criticized for how he handled sexual harassment claims at the network.
Shine worked closely with Ailes, and was named co-president of the network after the chairman's ouster.
Reaction to Shine's hiring included some negative responses from those who used to work for him or Fox News.
Last year, Gabriel Sherman wrote an article for Vanity Fair revealing that Shine was a defendant in a federal lawsuit filed by Andrea Tantaros, a former Fox News host.
Shine is a close friend of one of Trump's biggest supporters on the Fox network, conservative evening news commentator Sean Hannity.
HuffPost reported on Thursday that Shine's wife, Darla Shine, frequently attempted to discredit sexual harassment accusers at Fox News on Twitter.
Trump himself has been accused of sexual misconduct and assault by at least 16 women - and has been recorded bragging about such conduct.
Shine, who was the right-hand man of Roger Ailes, will assume the duties of Hope Hicks, who quit in March. Shine has never made clear what role - if any - he played in the cover-up of the inappropriate actions of Ailes and Fox News one-time star Bill O'Reilly, who was also fired after it was revealed he had settled a number of sexual harassment lawsuits.
"On your marks, get set.... how long till the liberal media and snowflakes start taking shots at the great Bill Shine?".
Shine is married to Darla Shine, a former Fox News TV producer.
Current press secretary Sarah Sanders has come under increasing scrutiny in the wake of President Trump's zero-tolerance policy for illegal crossings on the southern USA border.
