Colorado Sen. John Hickenlooper (D) said Wednesday he will run for reelection just once.

“I’m only gonna do two terms,” Hickenlooper told Punchbowl News’s Andrew Desiderio. “I’ve said it first here, two-term limit, oath of conscience.”

Hickenlooper, the state's former governor, gained a seat in the upper chamber by way of winning a key race against former Sen. Cory Gardner (R-Colo.) in 2020.

“There should be more people that are involved in local, municipal politics and governing and state politics and governing, who [get] into the Senate so that they bring those experiences with ‘em,” said Hickenlooper, who has also served as mayor of Denver.

Hickenlooper briefly ran for president in 2020.

He quickly backed Vice President Harris in her campaign for the presidency after President Biden announced he was leaving the race in late July.

“Vice President Harris is already uniting the Democratic Party, just as she will unite America,” Hickenlooper said in a post on the social platform X last month. “She has been President Biden’s copilot for these amazing four years and we can’t wait to do everything we can to help her win.”
