President Trump tweeted Friday afternoon that Secretary of Homeland Security John Kelly will be replacing Reince Priebus as White House chief of staff.

Priebus was tapped for the post one week after Trump defeated Hillary Clinton last November. His ouster comes on the heels of a public feud with White House communications director Anthony Scaramucci, whose appointment last Friday led to the resignation of Sean Spicer. Scaramucci spent his first week on Pennsylvania Avenue accusing Priebus of leaking information to the media, calling him a "fucking paranoid schizophrenic" who "[cock-blocked]" him in an explosive interview with Ryan Lizza of The New Yorker that was published on Thursday.

Twenty-four hours later, Priebus was on his way out of the White House. The former Republican National Committee chairman resigned from his post at the RNC in November to join Trump's staff.

With Priebus and Spicer, both former RNC leaders, pushed out of their positions in less than one week, the staff shakeup constitutes a major victory for Scaramucci, a man with a history of donating money to Democratic candidates who both men reportedly did not want Trump to hire. Scaramucci, for his part, is seen as a diehard loyalist to the president's agenda, seemingly intent on leveraging a powerful influence on the administration.

"I would like to thank Reince Priebus for his service and dedication to his country. We accomplished a lot together and I am proud of him!" Trump tweeted on Friday evening.

In a joint appearance with Steve Bannon at CPAC in February, Priebus emphasized the importance of conservatives "sticking together."

"We have to stick together and make sure that we've got President Trump for eight years," Priebus said. "And he's somebody that we know that we're going to be very proud of as these things get done. But it's going to take all of us working together to make it happen."

Whether or not Priebus decides to continue that mission outside the White House is yet to be determined, but if Scaramucci has any say in the matter, it's unlikely the former chief of staff will have any influence over Trump's agenda.
