“You can call it a dud I suppose if you’re talking about Broadway values or something,” Raskin, who sits on the House Judiciary Committee, told Hill.TV, referring to criticism from political pundits on both sides of the aisle.

“But if you’re looking at the Constitution, I think it was a very emphatic step forward in terms of our understanding of criminal misconduct in the administration,” he continued. “There are specific allegations of criminal misconduct — high crimes and misdemeanors outlined in the report and there are some critical figures we need to hear from.”

Raskin, a member of the congressional progressive caucus who supports pro-impeachment efforts, echoed calls from fellow House Democrats, saying lawmakers still need to hear from former White House Counsel Don McGahn.

During Mueller’s nearly two-year investigation, McGhan had told investigators that the president, on multiple occasions, ordered him to fire the special counsel. Trump has repeatedly disputed these claims, saying he “was never going to fire Mueller.”

“We need to get Don McGahn to come and testify before a committee — the administration is fighting that,” he told Hill.TV, adding that the move is “unacceptable.”

Raskin’s comments come after House Judiciary Committee Chairman Jerrold Nadler Jerrold (Jerry) Lewis NadlerDemocrats shoot down talk of expanding Supreme Court Schumer: 'Nothing is off the table' if GOP moves forward with Ginsburg replacement Top Democrats call for DOJ watchdog to probe Barr over possible 2020 election influence MORE (D-N.Y.) announced on Wednesday that the House panel plans to go to court to enforce a subpoena seeking McGahn’s testimony before Congress.

McGhan was subpoenaed by the committee earlier this year over the Russia probe, but President Trump later instructed his former top advisor to ignore the subpoena in May. At the time, the administration had argued that McGhan and other top presidential advisors were “absolutely immune” from congressional testimonies.

A growing number of Democrats have come out in support of impeachment in light of Mueller’s marathon testimony before lawmakers this week.

So far, more than 90 lawmakers have called for an impeachment inquiry, but it’s still less than half of the 234-member caucus.
