In a revealing interview with Axios, President Trump’s attorney, Rudy Giuliani gave insight into some of Special Counsel Robert Mueller’s questions and remained confident that they would find no evidence of collusion between the Trump campaign and Russia.

The President submitted his written answers to Mueller’s questions yesterday, and while reluctant to give specifics on the questions, Giuliani did concede that the Special Counsel asked about the following two topics: Donald Trump Jr.’s infamous meeting with Russians at Trump Tower and the Russian hacks during the campaign that followed Trump’s July 27, 2016 press conference in which he said, “Russia, if you’re listening, I hope you’re able to find the 30,000 [Hillary Clinton] emails that are missing.”

Giuliani said he doubts that Donald Trump Jr. would be indicted. “I don’t see what for,” he said. “The meeting turned out to be a big bust. … It’s a very unattractive crime [for a prosecutor] when somebody meets with you and then you don’t do anything.”

One topic Mueller did not ask about was obstruction of justice. “I can’t tell you he’s given up on obstruction,” said Giuliani.

“I don’t think he has any way to compel testimony on obstruction because the argument of executive privilege would be very, very strong. It all relates to a period of time after he was president. [A]ny question he has on obstruction, … [t]he president has given [the answers] in interviews, tweets. Other witnesses have given it to him. And the law definitely requires that if you’re going to subpoena a president, you have to show that you can’t get the information any place else,” he said.

According to Giuliani, the Mueller questionnaire “looked like a law school exam … one big long group of questions, that were multi-part questions.”

When if comes to collusion, Giuliani told Axios, “I don’t think they have any evidence of collusion of any kind. I think their obstruction case, as a legal matter, doesn’t exist.”

When asked if Mueller would subpoena the president, the attorney responded, “I think that he would not win a legal battle if he did that, and I think it would consume months.”
