NEW YORK (CBSNewYork/AP) – Comedian Jon Stewart crashed “The Late Show With Stephen Colbert” last night to continue his lobbying of Congress to pass a bill that covers health care costs for 9/11 first responders.

Stewart has been on a blitz this week to urge Congress to pass a permanent renewal of the Zadroga Act.

The law expired last month but has enough funding to last another year.

Proponents of the law are seeking its permanent extension, but some Republicans have opposed that, saying they want a chance to periodically review it and make sure it’s operating soundly.

Stewart started out his appearance by walking on stage as Colbert was delivering his monologue. He began with an earnest appeal, which Colbert decried as “boring!”

“Sorry, I hate to go pro on you here, but you’ve been out of the game for a while. That’s got no zazz,” said Colbert. “No one’s going to listen to you, unless you, I don’t know how to put this, Trump it up a little.”

Colbert then put a wig on Stewart and used a bag of Cheetos as make-up to turn Stewart’s face orange.

“Now you’re ready for people to pay attention to your message,” Colbert said. “Bring the noise. Bring the Trump!”

Stewart then jumped into an over-the-top impersonation of Donald Trump.

“These 9/11 first responders are the most top-notch, first class, diamond-encrusted first responders heroes America can produce,” Stewart said. “Don’t let Congress play politics with this necessary bill.”

Stewart went on to urge people to Tweet their representatives with #WorstResponders to urge them to pass the bill.

Stewart was a guest on “The Daily Show With Trevor Noah” on Monday night for the same reason.

Noah took over as host of “The Daily Show” in September, succeeding Stewart, who stepped down in August after 16 years.
