Democrat Sen. Martin Heinrich wrote, this dismissal "smacks of President Nixon's Saturday Night Massacre." MSNBC anchor Brian Williams dubbing it "what may become known as the 'Tuesday afternoon massacre.'"
Democrat Rep. Eric Swalwell weighing in saying, "This is an abuse of power, unlike anything we have seen since President Nixon."
Senate Minority Leader Chuck Schumer added a similar sentiment, asking, "Were these investigations getting too close to home?"
Not taking too kindly to these comparisons, the Nixon Library tweeted, "FUN FACT: President Nixon never fired the Director of the FBI." The last and only other president to fire an FBI director was Bill Clinton in 1993 when William Sessions refused to step down amid ethical concerns.
"President Trump's firing of Director Comey sets a deeply alarming precedent as multiple investigations into possible Trump campaign or administration collusion with Russia remain ongoing, including an FBI investigation," Democratic Sen. Ed Markey said. "This episode is disturbingly reminiscent of the Saturday Night Massacre during the Watergate scandal and the national turmoil that it caused."
Firing Comey can't end probe of Trump-Russia connections. Congress must keep up the pressure.
