Washington (CNN) Former Trump campaign adviser George Papadopoulos, who pleaded guilty in 2017 to lying to the FBI about his contacts with individuals tied to Russia during the 2016 campaign, is running for Congress in California.

Papadopoulos filed paperwork Tuesday to run as a Republican in California's 25th District following Democratic Rep. Katie Hill's resignation on Sunday amid allegations of improper relationships with staffers.

While Papadopoulos has not publicly issued a statement announcing his congressional bid, he had repeatedly teased a potential campaign in recent days on Twitter ahead of Tuesday's Federal Election Commission filing.

"Announcement soon on my interest in Katie Hill's soon to be vacant seat in the 25th district!" he tweeted Tuesday night. After Hill announced her resignation Sunday, Papadopoulos tweeted that he was "smelling blood in the water."

"California's 25th congressional district is wide open for the taking. Someone has to step up. I love my state too much to see it run down by candidates like Hill," he said. "All talk, no action, and a bunch of sell outs."
