Rudy Giuliani on Wednesday estimated that the ultimate decision on whether President Trump will give testimony to Special Counsel Robert Mueller will come in the next week or two.

The president has said that he would like to testify with Mueller -- who is investigating Russia's meddling in the 2016 election -- but Donald Trump Jr. doesn't think that's a good idea.

"I don't trust these people as far as I can throw them," Trump Jr. said of Mueller's team on "Fox & Friends." "I wouldn't sit down with them."

Echoing an argument that has repeatedly been made by Fox News senior judicial analyst Judge Andrew Napolitano, Trump Jr. pointed out that any slight misstatement or slip-up by Trump could be construed as a lie to a federal official in a formal investigation, which is a felony.

"I wouldn't do it. I think it'd be stupid," Trump Jr. said. "It's not about collusion anymore. It's, 'Can we get him to say something that may be interpreted as somewhat off or inaccurate? And after 50,000 questions maybe you make a mistake, and that's how we get you.'"

He said the whole Russia investigation has devolved into an attempt to find something to undermine a duly elected president, which he said is "disgusting."
