Video: Mark Levin, Dan Bongino, and Joseph diGenova dissect the Mueller Russia investigation.

LevinTV host Mark Levin interviewed former Secret Service agent Dan Bongino and former U.S. attorney Joseph diGenova on his weekly Fox News program, “Life, Liberty & Levin.”

“We’re here on very serious business,” Levin began. He asked his guests about two Department of Justice memoranda, one from the Nixon administration and one from the Clinton administration, that conclude that a president of the United States cannot be indicted by a special counsel.

“I don’t think there’s any question that the Mueller investigation as it sits now is illegitimate,” diGenova said. He explained that the appointment of special counsel Robert Mueller by Deputy Attorney General Rod Rosenstein did not name a crime for Mueller to investigate, raising serious problems. “It named nothing. This was a way for the department under Rosenstein to avoid responsibility for conducting an inquiry,” he said.

With no crime being investigated, diGenova said that having President Trump sit down with Mueller to answer his questions would be a waste of time for both Trump and the country. “I think the president should fight to the very end any subpoena issued by the special counsel,” he concluded.

Levin asked Bongino if he thought the Mueller probe is putting together a case for impeachment against Trump. Bongino thinks it is, but he went further, running through the prosecutors Mueller has hired and their anti-Trump, pro-Clinton biases.

“I think the entire Mueller operation, Mark, is a smokescreen to keep the attention on Donald J. Trump and to keep the attention away from the crimes committed with the Clinton operation and … the Obamagate spying scandal as well,” Bongino said.
