Donald Trump returned to Twitter to welcome John F. Kelly as the new White House chief of staff, taking over the seat previously occupied by Reince Priebus. The U.S. president said he personally appointed the Secretary of Homeland Security to take the office on July 31.

POTUS welcomes new White House member

In a separate tweet, Donald Trump thanked the outgoing chief of staff for his service and dedication since he took the job in January. The POTUS even commended Reince Priebus for being a "good man" and turned to talk about his expectations from John F.

Kelly.

The U.S. president labeled Kelly a "star" and a "great American" whom he expects to do well in his new responsibility at the White House.

Scaramucci targets Priebus on alleged WH leak

The transition came after Anthony Scaramucci slammed the outgoing chief of staff for allegedly leaking information from the White House. The new communications director said Reince Priebus should provide his own version of the story if he wants to clear his name from the issue.

The newly-installed communications director explained he could only speak for his own actions and not on behalf of the outgoing chief of staff. Hence, he wants to give Reince Priebus a chance to provide his reasons that would prove his innocence over the alleged leakage.

Anthony Scaramucci even hinted that there are "senior leakers" in the White House.

His interview took place after the communications director wrote a controversial post on social media where he tagged the official Twitter accounts of FBI, Department of Justice, and Reince Priebus.

After he had been questioned for seemingly threatening the outgoing chief of staff, Anthony Scaramucci addressed the issues surrounding his now-deleted tweet.

"They're all making the assumption that it's him because journalists know who the leakers are," he referred to the media.

Reince Priebus, on the other hand, confirmed to the Wall Street Journal that he resigned from his White House post on Thursday. In a statement, the former RNC chairman thanked Donald Trump for giving him the opportunity to serve the American people.

"I can’t think of a better person than John Kelly to succeed me, and I wish him God’s blessings and great success," he said, promising that he will continue to support Donald Trump and his administration.

When asked if the transition was decided by the outgoing chief of staff or the president, Sarah Huckabee Sanders said both parties were talking about the matter two weeks ago.
