An outraged Joe Scarborough sounded off on the failure of gun background checks in the Senate on Thursday's "Morning Joe."

The amendment — which would have extended checks to gun shows and online purchases — was a key provision in a series of proposals to reduce gun violence in the wake of the Newtown shooting. The bill failed 54 to 46, falling short of the 60 votes needed to break a filibuster.

Scarborough expressed his dismay with the senators who voted against the bill, which 90% of Americans support. He said that the right choice was "very simple," saying that background checks would keep guns out of the hands of terrorists, rapists and gang members.

Scarborough went on at length for nearly five minutes, blasting the senators who he said yielded to the NRA. He promised that they would "pay" a price for their vote, saying:

"I'm sick and tired of people on Capitol Hill that I've known for a long time that I've respected, I'm sick and tired of them insulting my intelligence, acting like I am stupid enough and you're stupid enough and 90% of americans are stupid enough to believe that this bill would lead to a national registry! I hear it all the time! Hey, the bill itself puts people in jail for up to 15 years. If they keep these names and start a national registry. It's offensive. It's stupid. And, Mika, you know what? In the long run, all of those people that voted for a more dangerous America are going to pay at the polls. Mark my words. This is going to come up and it's going to hit them in the face."

Co-host Mika Brzezinski agreed with Scarborough. Later, he turned to his own party, adding:

“Mark it down, this is going to be a turning point in the history of the Republican Party as well. And let those out there chattering, let them chatter away all they want to and scream like hyenas. … This party that killed this background check yesterday — this party is moving toward extinction. A new Republican Party is going to replace it. And this is going to be a vote that people will look back on and say, ‘That party, that extremism, that was unsustainable.’”
