U.S. Rep. Deb Haaland, one of the first Native American women to serve in Congress, will campaign for Democratic presidential candidate Elizabeth Warren in Colorado this week as the deadline to turn in ballots for the state’s March 3 Super Tuesday primary approaches.

Haaland, a national co-chair of the Warren campaign, was elected to represent New Mexico’s Albuquerque-based 1st Congressional District in 2018. A year ago, the member of the Laguna Pueblo people became the first Native American woman to preside over the U.S. House of Representatives.

A former state chair of the New Mexico Democratic Party, Haaland was a keynote speaker at the Colorado Democrats’ annual Obama Dinner last March. She sits on the House Armed Services Committee and is vice chair of the House Natural Resources Committee.

Haaland is scheduled to rally Warren supporters at a phone bank in Denver on Friday night and will help lead get-out-the-vote canvasses on Saturday in Boulder, Longmont and Denver.

Warren is one of eight major Democratic candidates on the ballot in Colorado’s presidential primary. She attracted thousands of supporters to a rally in Denver on Sunday, and a poll released Thursday showed the Massachusetts senator in second place with likely primary voters, behind Vermont Sen. Bernie Sanders, the national front-runner.

The phone bank Haaland will attend is at 7 p.m. Friday at the Warren campaign’s Denver field office, 3840 York St.

She’ll help launch a canvass at 9 a.m. Saturday at the Warren campaign’s Boulder office, 2850 Iris Ave., Suite M, and then do the same at 10 a.m. at a private home in Longmont. RSVP for the Longmont event here.

Next, Haaland will be on hand to kick off a canvass at 11 a.m. at a private home in Denver. RSVP for the Denver canvass here.
