Noted author, Harvard law professor, and critic of President Trump, Laurence Tribe offered his disparaging opinion of the Wednesday Robert Mueller hearings saying, "Much as I hate to say it, this morning’s hearing was a disaster."

"Far from breathing life into his damning report, the tired Robert Mueller sucked the life out of it," he continued. "The effort to save democracy and the rule of law from this lawless president has been set back, not advanced."

His criticism comes amid the former special counsel's appearances before both the House Judiciary and House Intelligence committees, which have received criticism due to his poor performance.

Tribe, 77, served as a judicial adviser to President Barack Obama's 2008 campaign and co-founded the American Constitution Society, the liberal counterpart to the conservative judicial-advising Federalist Society.

Tribe has called for impeachment proceedings against Trump on multiple occasions and has been tied to a website known to peddle unfounded conspiracy theories about the president. Tribe authored a 2017 opinion article in the Washington Post that highlighted what he believed to be "high crimes and misdemeanors" committed by Trump.

The legal scholar previously said of Mueller's investigation, "The consequential decision to impeach should not be made lightly. But Mueller's damning report is an invitation that Congress shouldn't refuse."

He recently co-authored a book titled, "To End a Presidency: The Power of Impeachment."
