Outgoing White House chief of staff John Kelly has reportedly begun revealing to friends his feelings about leaving the Trump administration.

CNN's Jim Acosta reported on-air Thursday that a source close to the White House said Kelly "is confiding to friends that he's relieved to be leaving" his post.

Tensions between Kelly and President Donald Trump were rumored for months prior to reports that the retired Marine general will be leaving the White House.

Veteran journalist Bob Woodward wrote in "Fear," his nonfiction book into the Trump White House, that Kelly thinks Trump is both "crazy" and an "idiot."

Amid ample speculation about who will replace Kelly, HuffPost reported that Trump's son-in-law Jared Kushner is in the running for the next White House chief of staff.
