Trump ousts Priebus, names Kelly as White House chief of staff

President Donald Trump took to Twitter to dismiss Reince Priebus as chief of staff and announced that he has appointed Homeland Security Secretary John Kelly to the job.

On Twitter, Trump wrote,"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...."

The dramatic move on Friday comes amid a long-simmering feud between Priebus and new White House communications director Anthony Scaramucci, who lambasted him in an interview with The New Yorker this week.

Reince Priebus said he resigned on Thursday.

Trump tweeted, "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! ...and a Great Leader. John has also done a spectacular job at Homeland Security. He has been a true star of my Administration."

"John Kelly will do a fantastic job. Gen. Kelly has been a star, done an incredible job thus far, respected by everybody. He's a great American," Trump told reporters.

Priebus had initially tried to block Scaramucci from an earlier post in the White House.
