Though Trump frequently vents about senior aides, he is often loath to fire staffers.
Mr Kelly initially called Mr Porter "a man of true integrity and honour" after the Daily Mail reported the ex-wives' allegations on Tuesday.
In a letter to House Intelligence Committee Chairman Devin Nunes, White House counsel Don McGahn said Mr Trump had decided against approving public release of the memo "because the memorandum contains numerous properly classified and especially sensitive passages".
'And I think you have to remember that.
More than 25 years before he was President of the United States, Donald Trump was placing ads in New York City papers calling for the execution of five black and Latino teens accused of raping a white woman in Central Park.
Senior aides knew for months about the allegations levied against Porter, even as his stock in the West Wing continued to rise, multiple sources have told CNN. "And we hope he has a wonderful career", Trump said. Again, Pence highlighted the generosity of the President for allowing him to represent America on the global stage, and reiterated that staffing issues would be dealt with when he returned to the White House.
Speaking to thousands of fraternity and sorority leaders in Indianapolis, former Vice President Joe Biden blasted the president for wishing Porter well and saying he was good at his job.
When the allegations first emerged against Porter a number of senior aides rallied around him, and the White House acknowledged that personal relationships may have played a role in their response.
Ms. Trump, who hired Ms. Hicks several years ago to work for her company before Ms. Hicks was tapped to serve on the Trump campaign in 2015, said Ms. Hicks was a "team player" who'd earned the president's confidence.
In the Oval Office on Friday, President Trump praised his former aide.
On Wednesday, after the photo of the black eye was published, White House Press Secretary Sarah Sanders echoed Kelly's initial remarks, saying Kelly has had confidence in Porter's abilities. Why not bring him back?
"I've had a lot of mentors and people who have been interested and helpful and useful in my life", Porter said.
Porter resigned Wednesday in the aftermath of his two ex-wives describing his alleged abuse. You wanted the Trump show in the White House? "I don't think I'm being fired today. And, you know, you have to listen to him". A golden parachute softens any fall.
The episode has thrust Trump's senior-most aides, many of whom have already been embroiled in controversy related to special counsel Robert Mueller 3rd's Russian Federation investigation, into yet another crisis.
While Kelly's fate is in question, sources familiar with the matter said they did not believe his departure is imminent. All those possibilities, though, point to the most important question of all: Whom does John Kelly see when he looks at Donald Trump? He has floated names like Mick Mulvaney, the current Office of Management and Budget director, as well as top economic adviser Gary Cohn, Rep. Mark Meadows of North Carolina, and Rep. Kevin McCarthy of California, The New York Times and ABC News reported.
