Judge Nap: Mueller's Probe Is 'Gearing Up and the President Remains in His Crosshairs'

Judge Nap: Rick Gates Is Likely Providing a 'Treasure Trove' of Info to Mueller

In the wake of the news that attorneys Joe diGenova and Victoria Toensing cannot join President Trump's legal team in the Russia investigation, Judge Andrew Napolitano is cautioning the president to take Special Counsel Robert Mueller's probe seriously.

On Sunday, Jay Sekulow, counsel to the president, said "conflicts" prevented diGenova and Toensing from joining Trump's team, an announcement that came just days after John Dowd, the top member of the team, resigned.

Napolitano explained that diGenova and Toensing's law firm has represented other clients in Mueller's investigation, including former Trump campaign adviser Sam Clovis, a witness who's testifying against the president.

"Bob Mueller has, as I said, 13 federal prosecutors -- experienced prosecutors -- and 30 FBI agents," Napolitano said. "The president has one full-time and one part-time lawyer. That's it."

He said that's "unbelievable," and Trump must take seriously Mueller's investigation into whether the 2016 Trump campaign colluded with Russia. Napolitano said Trump's team or diGenova should have known about the conflict before reports surfaced that he would go to work for the president.

Trump boasted on Twitter on Sunday that many lawyers -- with the prospect of “fame and fortune” -- want to represent him in the Russia collusion investigation, amid news reports that he cannot hire top-rate lawyers to work on the case.

Napolitano has repeatedly warned the president that sitting down with Mueller and his investigators would be a grave mistake. See him explain why.
