Call it "The Gang Goes to California" — members of the long-running comedy "It's Always Sunny in Philadelphia" will join a Golden State Democrat on the campaign trail with just days to go before the midterms.

Cast members will join Katie Hill, who is running for Congress in California's 25th District, for a canvassing event on Saturday, according to an invitation released Friday.

It wasn't clear which members of the cast would be attending the event, and a request for comment to Hill's campaign was not immediately returned.

"Join cast members of 'It's Always Sunny in Philadelphia' and our grassroots supporters in Simi Valley to kick off our 12PM canvass on Saturday, November 3! We'll start with a quick training before heading out into the community to knock on doors and spread the word about Katie and the November 6th general election," reads an invitation posted by Hill's campaign.

Hill is running in a close race against incumbent Rep. Steve Knight (R), and has a 63 percent chance of winning the district, according to a FiveThirtyEight analysis of the race. The most recent poll in the race showed Knight leading Hill by single digits among likely voters.

Democrats are looking closely at Knight's district as the party seeks to reclaim 23 seats in the House to retake the chamber during next week's midterm elections. A recent generic ballot poll released this week found Democrats with a single-digit advantage over Republicans for control of the lower chamber

Former President Obama visited the state earlier this year to campaign for Democratic House candidates in the state, urging his party to reach out to independent voters and Republicans as well as Democratic loyalists.

“We’re not just reaching out to true-blue, die-hard Democrats. I want to talk to independents who may have felt cynical about politics generally, but now you have candidates here who, regardless of party affiliation, you can say, ‘That person’s going to fight for me,' " the former president said in September.
