US President Trump dismisses reports of chaos at White House

President Donald Trump is insisting there is no chaos in his White House.

While Trump is looking for a reset, he pushed back against criticism of his administration on Twitter Monday. He said: "Highest Stock Market EVER, best economic numbers in years, unemployment lowest in 17 years, wages raising, border secure, S.C.: No WH chaos!"

Retired Gen. John Kelly, previously the Homeland Security secretary, takes over Monday from the ousted Reince Priebus, bringing his military experience to an administration weighed down by a stalled legislative agenda, a cabal of infighting West Wing aides and a stack of investigations.

Kelly's success in a chaotic White House 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 will have any influence over the president's social media histrionics.

Former Trump campaign manager Cory Lewandowski, who was ousted from the campaign in June 2016, said on NBC's "Meet the Press" that he expected Kelly would "restore order to the staff" but also stressed that Trump was unlikely to change his style.

"I say you have to let Trump be Trump. That is what has made him successful over the last 30 years. That is what the American people voted for," Lewandowski said. "And anybody who thinks they're going to change Donald Trump doesn't know Donald Trump."

Kelly's start follows a tumultuous week, marked by a profane tirade from the new communications director, Trump's continued attacks on his attorney general and the failed effort by Senate Republicans to overhaul the nation's health care law.

In addition to strain in the West Wing and with Congress, Kelly starts his new job as tensions escalate with North Korea. The United States flew two supersonic bombers over the Korean Peninsula on Sunday in a show of force against North Korea, following the country's latest intercontinental ballistic missile test. The U.S. also said it conducted a successful test of a missile defense system located in Alaska.

Sen. Dianne Feinstein, D-Calif., said on CBS' "Face the Nation" that she hopes Kelly can "be effective," and "begin some very serious negotiation with the North and stop this program."

Another diplomatic fissure opened Sunday when Russian President Vladimir Putin said the U.S. would have to cut its embassy and consulate staff in Russia by several hundred under new sanctions from Moscow. In a television interview, Putin indicated the cutback was retaliation for new sanctions in a bill passed by Congress and sent to Trump.

Trump plans to sign the measure into law, the White House has said. After Putin's remarks, the State Department deemed the cutbacks "a regrettable and uncalled for act" and said officials would assess the impact and how to respond to it.

While Trump is trying to refresh his team, he signaled that he does not want to give up the fight on health care. On Twitter Sunday, he said: "Don't give up Republican Senators, the World is watching: Repeal & Replace."

Trump's tweet came before the swearing-in of a new chief of staff. Ret. Gen. John Kelly will take over from Reince Priebus.

Over the past week, Trump's new communications director, Anthony Scaramucci, attacked Priebus in a profanity-laden tirade, Trump drew criticism for his public attacks on Attorney General Jeff Sessions and the latest effort by Senate Republicans to overhaul the nation's health care law failed.
