Colorado Democrats will get a chance to see U.S. Rep. Alexandria Ocasio-Cortez in September when the freshman congresswoman headlines the annual Boulder County party fundraiser.

Ocasio-Cortez, D-N.Y., will be joined by Rep. Joe Neguse, a Democrat from Lafayette, at the 44th annual Truman Dinner on Sept. 21 at the University of Colorado, according to a news release from Boulder County Democrats.

“Congresswoman Ocasio-Cortez is not only a great friend but an amazing colleague whose ability to speak truth to power has inspired millions of people across our country, including many here in Colorado,” Neguse said.

The Truman Dinner brings together Democrats from around Colorado and features scholarships, awards, auctions and speakers. Tickets go on sale at noon Monday, Aug. 19.

Ocasio-Cortez, 29, has quickly become one of the most vocal members of the Democratic party’s new wave of progressive members after her shocking upset victory over longtime Rep. Joe Crowley last year.

She has led the charge on progressive policies such as the Green New Deal and Medicare for All.
