Sen. Michael Bennet, D-Colo.

U.S. Senator Michael Bennet, D-Colorado, announced Thursday that he’s seeking the Democratic nomination for president.

Bennet is the second Coloradan to join the crowded Democratic field following former Gov. John Hickenlooper, who announced his campaign early last month.

Bennet had been mulling a run, but was diagnosed with prostate cancer earlier this year. He had successful surgery last month.

Bennet said economic mobility and health care are issues he’ll be focusing on in his campaign.

"I think this country faces two enormous challenges, one is a lack of economic mobility and opportunity for most Americans and the other is the need to restore integrity to our government," he said in an interview Thursday morning on CBS.

He cited having health care during his cancer treatment as part of his inspiration to run.

“The other reaction I had was to think about what it would feel like to get a diagnosis like that and to not have insurance, and to know that this president has worked so hard since he’s been president to take insurance away from people in America,” Bennet said.

Bennet is among at least 22 Democrats to officially join the race or exploring a run.

“Michael Bennet is just another tax-and-spend liberal with no chance of becoming president,” Republican National Committee communications director Michael Ahrens said in a statement. “Bennet hasn't gotten anything done after more than a decade in the Senate, and unfortunately for him, the ‘unknown, no-accomplishments lane’ of the Democratic primary is already full.”
