Trump appears increasingly frustrated about the investigation — which he routinely calls a “witch hunt” — as the probe extends into a second year and interferes with his administration.

Giuliani was hired in recent weeks to try to bring the investigation to a close and perhaps arrange an interview between Trump and Mueller, as a final step.

However, he and others on Trump’s legal team have been wary about allowing Trump to talk, for fear federal investigators might try to set a legal trap.

“We’re not going to sit him down if it’s a trap for perjury,” Giuliani said Sunday. “He wants to explain that he did nothing wrong.”

To be sure, Trump has consistently said he didn’t meddle with Russia to influence the 2016 presidential election. And he argued that the investigation has moved beyond its original intent to include the business dealings of the president’s business associates.

“This is rigged, you’ve got 13 Democrats, no collusion,” Giuliani said. “They are focused on things that didn’t happen.”

He also said the president is “not going to fire anybody” because that would make him look like a victim.

Giuliani also said that the former administration should have informed Trump that it was looking at Russia meddling during the 2016 race and was surveilling his campaign.

“Some of it is Mueller’s fault (but) it completely taints his investigation,” Giuliani said. “The whole thing with this investigation that was going on, which we consider spying, was done before Mueller got involved. But it completely taints his investigation.”
