Rep. Tom O’Halleran (D) announced in a tweet on February 7 that he would be running for re-election in 2020. He has represented Arizona’s 1st Congressional District since 2017.

He last won re-election in 2018 when he captured 53.8 percent of the vote to defeat Wendy Rogers (R). A former Flagstaff city council member, Eva Putzova (D), has already announced her bid for O’Halleran’s seat in 2020.

O’Halleran was chosen to serve as the policy co-chairman of the Blue Dog Coalition in November 2018. In the 116th Congress, he will serve on the House Energy and Commerce Committee and the House Committee on Agriculture.

Prior to his election to the U.S. House, O’Halleran served in the Arizona State Senate as a Republican, where he represented District 1 from 2007 to 2009, and in the Arizona House of Representatives from 2001 to 2006. He ran for U.S. Congress as a Democrat in 2016 after leaving the Republican Party in 2014.
