 WASHINGTON—Chief of Staff John Kelly is expected to leave his post soon, people close to the White House said, as President Trump begins putting into motion a broad shake-up of his administration ahead of his re-election campaign and heightened scrutiny from Congress. The expected departure would end a tumultuous tenure for Kelly, who was brought on to bring order to the White House but whose time as chief of staff has often been marked by the same infighting and controversy that has largely defined Trump's presidency from its beginning. Potential replacements include Nick Ayers, Vice President Mike Pence's chief of staff, who is still seen as a leading contender 
 
 Kelly has been on the verge of resigning or being fired before, only to bounce back every time. Still, as Kelly passed the one-year mark in July, administration officials said Trump had asked the chief of staff to stay on through the 2020 election.
– It's official: John Kelly is leaving the White House. "John Kelly will be leaving toward the end of the year," said President Trump while heading out for the Army-Navy game Saturday, USA Today reports. Rumors had been swirling after White House sources said Kelly was on his way out—and Nick Ayers, Vice President Mike Pence's most senior aide, might be taking his place, per the Wall Street Journal. "Stop calling John [Kelly] for anything," President Trump was quoted as saying. "Call Nick. He's my guy." But Trump aides warned that Ayers was more a Pence advocate, and Secretary of State Mike Pompeo reportedly criticized Ayers' foreign-policy skills. On the plus side, Ivanka Trump and Jared Kushner—who have bristled under Kelly's command-and-control style as chief of staff—are said to be pro-Ayers. Kelly repeatedly clashed with Trump and lost some West Wing authority during his 17-month tenure, per CNN. A former Marine Corps general, Kelly imposed discipline on a freewheeling White House but saw Trump work around his who-gets-to-see-Trump-when rules. Kelly also made his own problems, erupting in a profanity-laced exchange with national security adviser John Bolton, engaging in a "near brawl" with informal Trump adviser Corey Lewandowski, slamming Rep. Frederica Wilson with false information, and apparently mishandling the abuse scandal around ex-staff secretary Rob Porter. Kelly also denied reports that he'd called Trump "an idiot" and considered himself "the lone bulwark against catastrophe" in Trump's White House. Trump called Kelly "a great guy" in announcing his departure.
