“But you can be sure that we’re only going to do that if we feel there’s a way to shorten this thing,” Giuliani said Thursday morning on Fox News's “Fox & Friends.”

"@POTUS wants to testify. He wants to give his side of the case, which he believes is the truthful one. He keeps saying to me, 'I've never talked to any Russians... What is this nonsense about Russians?'"

The former New York City mayor joined Trump’s legal team last month to lead it through the Justice Department’s investigation into Russia interference during the 2016 presidential election.

“My job is not to lean over and let them beat the hell out of us,” Giuliani said on Thursday. “That’s what was going on before I got here.”

Giuliani also again insisted that the only thing Mueller can do is “write a report” at the conclusion of his investigation.

On Wednesday, Giuliani told CNN that Mueller’s team told Trump's camp that it can't indict a sitting president.

“They can’t indict. At least they acknowledged that to us, after some battling, they acknowledged that to us,” Giuliani said.

Sen. Richard Blumenthal (D-Conn), however, responded to Giuliani late Wednesday, saying that Trump could still face an indictment.

"The president is not above the law, and an indictment — if that's the course that Robert Mueller chooses to go — I believe would be upheld by the courts," Blumenthal, a former Connecticut attorney general, told CNN.
