Jon Stewart returned to "The Daily Show" on Monday to take on the issue of medical support for 9/11 first responders.

Fans of "The Daily Show" have missed Stewart since he handed the show over to new host Trevor Noah. Though Stewart returned as a guest and not a host last night, fans were still excited to see him mount a comeback.

According to CNN Money, the former host finally made his return to the show, but on the opposite side of the desk, though he did try to take his old seat back at one point.

Stewart returned to interrupt an opening monologue by Noah about iguanas, "king of the reptile kingdom." The two started out with a few comic exchanges, with Noah even greeting him as "Papa," before getting down to business.

The elder host began his usual comic mocking of Republican politicians, attempting to finally bring to light an issue that should have been a no-brainer from the very beginning. Stewart mercilessly called out and shamed Senate Majority Leader Mitch McConnell among others for repeatedly failing to extend the Zadroga Act, a bill that provides aid to first responders, who helped people in the critical hours of 9/11.

Stewart pointed out McConnell and other Republicans have repeatedly said they would extend the bill if they could get it "paid for," which is basically a way to pass off blame on the bill's extension. But then Stewart showed how McConnell reacted to a similar issue in his home state of Kentucky: the plight of people who worked at nuclear power plants. The only difference was: McConnell found a way to get that second bill funded, starkly implying that his motives in both matters were purely political.
