Thomas Charles O'Halleran (; born January 24, 1946) is a member of the United States House of Representatives, representing Arizona's 1st congressional district. Beginning his political career as a Republican, he serves as a member of the Democratic Party.
O'Halleran served with the Chicago Police Department from 1966 to 1975. He then became a member of the Chicago Board of Trade, operating his own futures trading business with a focus in futures contracts on 10-year U.S. Treasury notes.
O'Halleran, then a Republican, served in the Arizona House of Representatives from 2001 to 2006. He then served in the Arizona State Senate, representing the 1st District from 2007 to 2009. In a 2008 primary election, he was unseated by Steve Pierce.
In 2014 he left the Republican Party, citing its policies on education, water, and child welfare as reasons for his resignation. He then ran for the 6th District State Senate seat as an Independent, losing by 3%.
He explained his switch of party affiliation as a result of his positive attitude toward government, and, in particular, of his support for government regulations that would increase the use of wind and solar energy.
On August 30, 2016, O'Halleran beat Miguel Olivas in the Democratic primary. He faced Republican Paul Babeu and Green Party candidate Ray Parrish in the general election on November 8, 2016. O'Halleran won, receiving 51% of the vote to Babeu's 44%.
In March 2018, O'Halleran criticized the Trump Administration for seeking to cut funding for such agencies and programs as the Economic Development Administration, the Rural Business and Cooperative Service, the Manufacturing Extension Partnership, Community Development Block Grants, Rural Water and Wastewater Grants, Indian Community Development Block Grant, the Rural Economic Development Program, Essential Air Service, and Native American Housing Block Grants.
After the Stoneman Douglas High School shooting in Parkland, Florida, O'Halleran, who had long supported expanded background checks but opposed an assault-weapon ban, suggested he might shift toward a stronger position on gun control. "At times you have to look at yourself in the mirror and do the right thing and say forget about the political consequences," he said, but admitted he was concerned about those consequences.
When President Donald Trump ordered a travel ban on visitors and refugees from seven predominantly Muslim nations in January 2017, O'Halleran said that the order "does not represent our nation's values" and that it violated the Constitution and "the bedrock ideals of our democracy."
In April 2017, O'Halleran criticized Attorney General Jeff Sessions's tougher new guidelines on expelling illegal immigrants who belong to criminal gangs. "I have no problem with getting the felons out of the country," O'Halleran said. "But some of these people that they're taking out of the country, they have children that are Americans, and they have not had a violent felony conviction. Here we are, taking mothers away from their children."
O'Halleran was part of a group of Arizona Democrats who, in an August 2017 letter to President Trump, urged him not to pardon former Maricopa County chief Sheriff Joe Arpaio, who had been convicted in a federal court of racially profiling Latinos as part of border patrols. "It is imperative for a society to hold elected leaders to the highest level of accountability, and when they are convicted of crimes and lose the trust of the public, they must face their punishment," said O'Halleran. "As a former law enforcement officer, Joe Arpaio's abuse and exploitation of his power to target vulnerable communities is beyond egregious and tarnishes the sworn duty of our brave officers across Arizona."
