Assistant Watergate special prosecutor Jill Wine-Banks said on MSNBC's "The 11th Hour with Brian Williams" that Giuliani's recent comments about limiting the questions Mueller's team could ask Trump about collusion and obstruction could be a basis for that case.

"He said, 'Oh I'm fine with collusion because there’s no collusion, but obstruction, that’s a matter of interpretation,'" Wine-Banks said. "And it isn’t. Facts are a funny thing. The truth and the facts will come out, and I don’t think it’s going to show that it’s a matter of interpretation, but of guilt."

Wine-Banks also said that Giuliani is trying to control the public's understanding of the negotiations with Mueller's investigators, who are probing Russia's meddling in the 2016 presidential election and possible collusion between the Trump campaign and Moscow.

“You have unanswered accusations from Giuliani that Mueller cannot and must not answer because he’s acting appropriately,” she said. “Giuliani can say whatever he wants and then he can say, ‘And see how unfair it was, they didn’t want to agree to that, they said they would and then they wouldn’t.’"

She also argued that a New York Times report that Trump pressured Attorney General Jeff Sessions Jefferson (Jeff) Beauregard SessionsGOP set to release controversial Biden report Trump's policies on refugees are as simple as ABCs Ocasio-Cortez, Velázquez call for convention to decide Puerto Rico status MORE to reverse his recusal from the Russia investigation is another example of potential obstruction. The newspaper reported on Tuesday that Trump made the request of Sessions in March 2017.

Trump has repeatedly called the Mueller investigation a "witch hunt" and in recent weeks has accused the FBI of embedding a spy in his presidential campaign.

Giuliani said on Tuesday that Trump would not sit for an interview with Mueller until his legal team receives all documents related to the FBI's use of an informant.

“We need all the documents before we can decide whether we are going to do an interview,” Giuliani told The Washington Post.
