President Donald Trump's new chief of staff is entering a West Wing battered by crisis.
Retired Gen. John Kelly, previously the Homeland Security secretary, takes over Monday from the ousted Reince Priebus.
In an Oval Office ceremony, Trump predicts Kelly will do a "spectacular job."
The president denies there is "chaos" in the White House, despite a particularly tumultuous stretch. And he says things are going "very well."
Trump is declining to say just what Kelly will do differently from Reince Preibus, whom Trump ousted as chief of staff late last week.
Trump hopes Kelly can bring some military order to an administration weighed down by a stalled legislative agenda, a cabal of infighting West Wing aides and a stack of investigations.
Still, Kelly's success will depend on how much authority he is granted and whether Trump's dueling aides will put aside their rivalries to work together. Also unclear is whether a new chief of staff can influence the president's social media habits.
While Trump is trying to refresh his team, he signaled over the weekend that he does not want to give up the fight on health care.
