White House communications director Bill Shine has resigned and will serve as a senior adviser to President Trump's 2020 re-election campaign, White House press secretary Sarah Sanders announced Friday.

Details: The announcement didn't give a reason for Shine's departure. The bulk of Shine's career was spent as a producer and executive at Fox News, most recently serving as the network's co-president.

"Serving President Trump and this country has been the most rewarding experience of my entire life. To be a small part of all this President has done for the American people has truly been an honor. I'm looking forward to working on President Trump's reelection campaign and spending more time with my family."

— Shine

Catch up quick: Per a recent New Yorker article, Shine was yet another key figure in the "interlocking connections between the White House and 21st Century Fox."

Behind the scenes, via Axios' Jonathan Swan: Trump warmed to Shine initially, as Shine paid attention to details like lighting and set design, like a TV producer. Trump dug that. But it wasn’t long, according to a source with direct knowledge, before Trump began grumbling that his media coverage was as bad as ever.
