“He shouldn’t really [testify]. He already put out his report. He made his 10-minute statement and then said he wasn’t going to talk about it anymore because it’s not proper,” Giuliani said Sunday on John Catsimatidis’s radio show, referring to a press conference Mueller gave on his report that he said would be his final word on his two-year probe.

“But somebody must’ve persuaded him that he should comment some more. He’s already commented more than any prosecutor has ever commented about a case he didn’t bring. Let’s see what he says,” Giuliani added.

Mueller is slated to appear Wednesday before the House Judiciary and Intelligence committees to testify about his two-year probe into Russian interference in the 2016 election and possible obstruction of justice into subsequent investigations.

The former special counsel found insufficient evidence to bring charges against Trump or his closest associates over conspiring with Moscow in 2016 but declined to clear the president of any wrongdoing over allegations of obstruction of justice, outlining 10 “episodes” of possibly obstructive behavior.

But Mueller said he could not bring charges, citing existing Justice Department guidelines against indicting a sitting president.

Mueller has affirmed he will not go beyond the four corners of his report, though Democrats are eager for the opportunity for a national television audience to hear some of its more embarrassing details for the White House.

Giuliani, however, said Republicans will also take the opportunity to ask questions of Mueller casting his probe as an attempt to oust Trump.

“I think that Mueller is going to find out that, although he can’t talk about the investigation anymore than he has already disclosed, he’s going to be faced with a lot of questions he hasn’t answered before,” he said. “I’m quite convinced it was definitely an attempt to, first, stop Donald Trump from being president and then to remove him from office. There’s no doubt that was the motivation.”
