WASHINGTON — White House acting Chief of Staff Mick Mulvaney said Sunday that he didn’t offer President Trump a resignation letter after Thursday’s press conference about aid to Ukraine — as he defended his remarks at the event.

“No, absolutely not. Absolutely, positively not,” Mulvaney told Chris Wallace on “Fox News Sunday.” “Did I have a perfect press conference? No. But the facts are on our side.”

In the White House briefing room Thursday, Mulvaney said the administration held up military aid dollars to Ukraine in order to pressure the country’s government to investigate the hacking of the Democratic National Committee’s server during the 2016 election — which ABC News’ Jonathan Karl then called a “quid pro quo” in a question.

“We do that all the time with foreign policy,” Mulvaney responded.

The acting chief of staff on Sunday noted that he never called it a quid pro quo.

“I never said there was a quid pro quo because there isn’t,” he said Sunday. “Reporters will use their language all the time. My language never said quid pro quo.”

Mulvaney told Wallace the administration held back aid for “two reasons” — it was concerned about corruption and also wanted to see what other countries gave Ukraine.

“There was never any connection between the flow of money and the server,” Mulvaney said, referencing the DNC’s server that got hacked by Russians in the lead-up to the 2016 presidential election and was hidden in Ukraine.

On Thursday, Mulvaney had mentioned three reasons the money was being held up: “corruption in the country, whether other countries were participating in the support of Ukraine and whether they were cooperating in an ongoing investigation with our Department of Justice.”

“That’s completely legitimate,” Mulvaney said at the time.

On Sunday, he encouraged Wallace to “go back and look at that list of three things.”

“What was I talking about? Things that were legitimate for the president to do. No. 1, it is legitimate for the president to want to know what’s going on with the ongoing investigation into the server. Everybody acknowledges that. At least I think most normal people do,” Mulvaney said.

“No. 2, it’s legitimate to tie the aid to corruption. It’s legitimate to tie the aid to foreign aid to other countries,” he added. “That’s what I was talking about with the three.”

He again added, “I never said there was a quid pro quo, because there isn’t.”

“And Chris, you’ve been in these briefings, you know how back and forth it is, you know how rapid-fire it is. Look to the facts on the ground, things you can actually certify,” Mulvaney said. “What should put this issue to bed is that the money flowed without any connection whatsoever to the DNC server.”

It didn’t.

“Now you’re acknowledging it was for three reasons. If you held up the money for three reasons that’s a quid pro quo,” Wallace said. “Now maybe the president backed off that, but that was the proposition here.”

Mulvaney pushed back on that assertion.

“I’m not acknowledging there were three reasons,” he told Wallace.

“You said three reasons,” the “Fox News Sunday” host said.

“I recognize that. Go back to what actually happened in the real world. Go to the phone call. The president never mentions the aid on the phone call,” Mulvaney said. “We all know enough about this president that if he feels very strongly about something he’s going to put that out there directly and it didn’t happen.”

CNN reported Sunday that Mulvaney had been looking to exit his post, while White House adviser Jared Kushner had been looking for a replacement before the impeachment inquiry into President Trump began.

Mulvaney said he recognized that he didn’t “speak clearly” at the press conference Thursday, but added that his performance shouldn’t lose him his job.

“I still think I’m doing a pretty good job as the chief of staff and I think the president agrees,” Mulvaney said.

House Speaker Nancy Pelosi launched an impeachment inquiry after a whistleblower’s complaint about a July 25 conversation between Trump and Ukrainian President Volodymyr Zelensky.
