“Over my dead body,” Giuliani, the former New York City mayor and federal prosecutor said on “Fox News Sunday.”

Giuliani, who’d at times floated the possibility of a meeting in interviews over several months, didn’t answer directly when asked about a CNN report on Dec. 14 that Mueller wants to interview Trump in his investigation of Russia influence in the 2016 campaign.

In a separate interview on ABC’s “This Week” on Sunday, Giuliani was less definitive when asked whether it’s possible Trump will talk to Mueller. He cited an agreement with prosecutors allowing for a discussion about it after the president submitted written responses to questions last month.

“All I can tell you is the agreement contemplates our having discussions if there are any further follow-ups or questions, and there’s been no change in that agreement,” Giuliani said. “And when it’s concluded, we’ll tell you.”

While Trump submitted written answers to some questions, his legal team rebuffed Mueller on queries about whether the president sought to obstruct justice. The lawyers said the answers only cover events before Trump became president and Russian-related topics.

‘Serial Liar’

Sunday’s appearances on were Giuliani’s first since one Trump’s former lawyer and fixer, Michael Cohen, was sentenced on Dec. 12 to three years in prison for crimes that included hush-money payments to women who said they had affairs with Trump. Cohen has repeatedly said Trump directed the payments, which the president has denied.

The payments weren’t a campaign contribution and therefore not illegal, Giuliani said on ABC. He also called Cohen “a serial liar” with no evidence to back up what he’s saying. In an interview with ABC that aired Dec. 14, Cohen said “there’s a substantial amount of information that they possess that corroborates the fact that I’m telling the truth.”

In a Sunday tweet, Trump said Sunday that “Cohen only became a ‘Rat’” after the FBI “BROKE INTO” the lawyer’s office. In fact, federal officials had a warrant in that case.

On Fox, Giuliani appeared to joke that Mueller was interested in probing “several unpaid parking tickets back in 1986” — an apparent reference to his contention that Mueller’s investigation and the probe into Cohen have gone far beyond the original intent.

“The only thing left are the parking tickets and jaywalking,” Giuliani said on ABC when asked whether Mueller is almost done with his investigation.

Reflecting on the Cohen conviction and other pending matters, Republican Senator Susan Collins of Maine said Sunday on CNN’s “State of the Union” that “clearly, this was not a good week for President Trump.”

Given the array of “unanswered ethical, legal and factual questions,” it’s critical that Mueller “be allowed to complete his investigation unimpeded, so that we can have the full picture,” she said.
