Former Olympic athlete and Air Force veteran Eli Bremer just announced he is challenging Colorado Democrat Senator Michael Bennet in next year’s midterm elections.

Fox News reports:

“Having twice worn the uniform of our nation – in the military and in the Olympics – I am concerned that the country I have represented is being sold out by self-interested politicians,” Bremer said in a statement shared first with Fox News.

Bremer took aim at Bennet, charging that “in 12 years, he has authored one piece of legislation that has been signed into law. One.” And he vowed that “as the next U.S. Senator from Colorado, I will work for pragmatic solutions that positively impact Colorado and America.”

“I’m watching right now as our nation is sort of falling apart and saying, ‘I can’t sit on the sidelines anymore,’” he emphasized.

Bremer grabbed national attention as one of the lead athletes in the bipartisan Olympic reforms push in the wake of the USA Gymnastics sex abuse scandal. Bremer criticized Bennet, one of the founding chairs of the Senate Olympic caucus, charging that the senator refused to get involved. And Bremer argued that “we need a senator from Colorado who brings a healthy dose of common sense and traditional Colorado values and that’s just not where he (Bennet) is.”

Bremer worked on Trump’s successful 2016 campaign for the White House. Republicans see Colorado as a possible route to winning back the majority in the Senate. While the state has trended blue in recent years national Republicans still count the state as a lead target to flip some seats back to the GOP.
