John Oliver tore into Congress on Sunday night for failing to even make an effort to keep Donald Trump in check in wake of the President's decision to fire James Comey, the former director of the FBI.

"He fired the director of the FBI, at least partially due to unhappiness with the bureau’s investigation into his campaign’s possible collusion with Russia, which is both shocking and yet completely unsurprising. There’s really nothing Trump could do to genuinely shock me right now," the "Last Week Tonight" host said. "It is too easy to point at Trump being crazy. That’s what he does, it is not going to stop, and it’s going to be exhausting for everyone."

Oliver proceeded to call out exactly who is responsible for protecting the American people from a crazy POTUS.

"And that brings us to Congress: 534 people less annoying than Ted Cruz, and also, Ted Cruz," Oliver said. "It is time for each and every one of them to pick a lane here. They do have options. Obviously there are the investigations that are currently ongoing, but they could also press Deputy Attorney General Rod Rosenstein to appoint a special council within the Justice Department, but at the very, very least here, they need to acknowledge that what has happened is f--ked up and not continue to give non answers."

The comedian targeted House Speaker Paul Ryan, in particular, for refusing to comment on Trump's Twitter threat to Comey: "James Comey better hope there are no 'tapes' of our conversations before he starts leaking to the press."

"It’s honestly incredible to watch a man who spends 90 minutes every morning working out refuse to show any strength whatsoever," Oliver joked. "Apparently, no part of P90X targets the backbone."

"The point is, the Founding Fathers created the system of checks and balances to limit the power of the president - but it only works if someone f--king checks or balances," Oliver said. "And if you don’t, it’s no longer on Trump, it’s on you. Because when you’ve got the presidential equivalent of a five year old sh--ting on the salad bar of a Ruby Tuesday, at some point you stop blaming the five year old and you start blaming the people who are not stopping him. Stop that boy, that’s what I’m saying. Stop that boy now."
