After frequent conversations with Kelly, Trump recently warmed up to the idea of naming Kelly chief of staff to more effectively manage personnel and offered it to him earlier this week, a senior White House official said.
According to an anonymous advisor who spoke to the president about the New Yorker interview (which he reportedly enjoyed), Trump was "dismissive" of Priebus "for not returning fire" against Scaramucci in a public forum, or privately through an approved press leak.
US President Donald Trump on Friday ousted his beleaguered chief of staff Reince Priebus, replacing him with retired Marine Corps general and current Homeland Security Secretary John Kelly.
White House press secretary Sean Spicer resigned last week after Scaramucci was hired.
He praised the president and Kelly and declined to discuss the Scaramucci interview, saying, "I am not going to get into the mud". "I can't think of a better person than General John Kelly to succeed me and I wish him God's blessings and great success", he said.
Trump made the announcement via Twitter. "I think things are going well", he said a few days before the election. He and two other senior Trump aides, Stephen Miller and Dan Scavino, got into a van in Trump's motorcade at Joint Base Andrews in suburban Maryalnd shortly before Trump's tweet, then Miller and Scavino got out and entered a different vehicle.
"Reince Priebus has left it all out on the field, for our party and our country", Ryan said. He said he had tendered his resignation to the President on Thursday, the same day the newly-appointed White House Communications Director Anthony Scaramucci was quoted vowing to force the Chief of Staff out. "He has achieved so much, and he has done it all with class".More news: Vettel takes pole position for Hungarian Grand Prix

He retired from the military last year, wrapping up a three-year post as head of U.S. Southern Command, which spanned some of the more fractious debate over the Obama administration's ultimately failed attempt to close the detainee facility at Guantanamo.
Kelly acknowledges that when he took over DHS, his department was created to be less responsive to Congress and the press, something he realized over time he should work to correct. The Senate confirmed him as major general in 2007. He had been leading DHS' recent surge in efforts to crackdown on illegal immigration - a core campaign promise by Trump.
Trump has repeatedly praised Kelly for his operation of homeland security, including tighter border controls and a travel ban from six Muslim countries that is now the subject of a lawsuit.
On Friday afternoon, during a speech in Long Island, N.Y., Trump gave what now seem like foreshadowing remarks. Yet, just days after taking office, he had to lead the agency as it dealt with the chaos and confusion that ensued at airports in the US and around the world.
John Kelly has been toughened by war and tragedy. In April, he challenged lawmakers at Congress critical of the aggressive approach to immigration enforcement to either change the laws or "shut up".
As Homeland Security secretary, Kelly has taken the lead on some of Trump's most controversial policies, including his executive orders suspending the admission of refugees and temporarily barring visitors from several Muslim-majority nations. Ron Johnson said in a statement.
