President Donald Trump abruptly fired FBI Director James Comey, prompting practically every member of Congress to weigh in. Many — including some prominent Republicans — are furious, dubbing the dismissal “Nixonian” and “a constitutional crisis.”

Weeks before what some are now referring to as the “Tuesday Night Massacre,” the now-former FBI director confirmed to Congress that he was spearheading an investigation into possible ties between the Trump administration and Russian interference in the U.S. presidential election. On Tuesday, dozens of senators and representatives called for a special prosecutor to lead an independent investigation into those ties, saying Comey’s dismissal tainted the credibility of any future FBI-led investigations.

By late Tuesday evening, two Republicans and two Independents had joined the host of Democrats calling for an independent investigation.

Several Republican members of Congress also signaled their disapproval over the firing, though they held off on explicitly calling for an investigation, like Senate Intelligence Committee Chairman Sen. Richard Burr of North Carolina, who said in a statement that he was “troubled” by the firing, calling it a “loss for the Bureau and the nation.” Sen. Ben Sasse, a Republican from Nebraska, echoed Burr in calling the timing “very troubling.”

And Jeff Flake, a Republican senator from Arizona, said late Tuesday night that he had yet to find an “acceptable rationale” for firing Comey as Trump did.

At least one member of Congress did appear to support Trump’s move: Republican Sen. Roy Blunt, of Missouri, who said in a statement, “Many, including myself, have questioned his actions more than once over the past year.”

Kentucky Republican Rand Paul, the lone dissenting vote against Comey’s 2013 Senate confirmation as FBI director, said that Comey’s dismissal was urgently needed.

Other Congressional Republicans have tried to strike a more conciliatory tone by affirming the fundamental weirdness of Trump’s move to fire Comey, while respecting his authority to do so.

Sen. Marco Rubio praised Comey as “professional” and thanked him “for his service” in an interview with ABC News. He added that although the decision “surprised” him, he said Comey’s firing was “a decision the president’s made, and we’ll go from here.”

In his own statement, Sen. Bob Corker said that Comey’s “removal at this particular time will raise questions,” and that “it is imperative that President Trump nominate a well-respected and qualified individual to lead the bureau at this critical time.”
