Justice Democrats, a national progressive group, on Thursday endorsed Melat Kiros, a lawyer and barista, in her campaign against Democratic Rep. Diana DeGette in Colorado's 1st District.

Kiros received Justice Democrats' sixth endorsement against an incumbent this election cycle, highlighting the group's push for generational and ideological change in the Democratic Party. The push comes amid broader thirst for new leadership and younger elected officials among the party's rank-and-file voters.

"Voters in Denver, like across the country, are ready to turn the page on a Democratic Party that is failing to fight back against the Trump administration & corporate interests or deliver lower costs for everyday people. Melat is exactly the type of leadership we need right now — leadership rooted in her communities' lived realities that will never back down against the wealthiest or most well-connected interests," Justice Democrats Executive Director Alexandra Rojas said in a statement.

Kiros, 28, launched her campaign in July, vowing to tackle rising costs and fight back against President Donald Trump if she's elected. Her launch video featured clips of DeGette, 68, on CNN in the late 1990s, after she was first elected.

On Wednesday, Kiros told NBC News, "The No. 1 concern that I have is with affordability."
