Omar Montgomery, a candidate for Aurora mayor, picked up another high-profile Democratic endorsement in the reputedly nonpartisan office.

Montgomery announced the endorsement of former Obama Attorney General Eric Holder Jr. Friday morning.

“Aurorans have an opportunity to elect a proven leader who understands that fixing our broken democracy starts with a transparent local government that ensures all communities are properly represented and heard. Omar’s track record of community leadership shows me that he’s more than ready for this responsibility, and I urge voters to make sure he’s elected in November,” Holder said in a statement Friday.

In the six-way race, Montgomery is taking on former Republican U.S. Rep. Mike Coffman and former Republican and ex-City Council member Ryan Frazier. Montgomery leads the Aurora chapter of the NAACP. He is an educator at the University of Colorado Denver and director for the Center for Identity and Inclusion.

Holder was the country’s chief law enforcement official from 2009 to 2015.

Montgomery said he was “humbled and honored” by Holder’s nod.

He called Holder “a widely-respected national leader, President Obama’s AG, and now, a leading voice on issues like a fair census count, gerrymandering, and transparency in government.”

Montgomery continued, “We need to open the doors of our local government and to make our elections clean and fair. Mr. Holder knows that I will continue to advocate for fair representation as mayor of our beautiful Aurora.”
