Ed Pastor is married to Verma Mendez Pastor.
Pastor was born in Claypool, Arizona, as the oldest of three children. After high school, he was educated at Arizona State University. He became a chemistry teacher at North High School in Phoenix and later went on to work as deputy director of the community service group Guadalupe Organization Inc. After returning to ASU to earn a law degree, he became an assistant to Arizona Governor Raul Castro. In 1976, Pastor was elected to the Maricopa County Board of Supervisors, and he served three terms in that role as a county executive.
A Latino delegation from the US was invited to observe the February 25 1990 Nicaraguan elections. It was led by Congressman Esteban Torres of California, and coordinated by Antonio Gonzalez of the Southwest Voter Research Institute. The delegation included Ed Pastor (Phoenix County Supervisor), Dallas based journalist Mercedes Olivera, Brownsville attorney Linda Reyna, California businessman Michael Hernandez, San Antonio professor Avelardo Valdez.
Since being elected to the United States House of Representatives, Congressman Pastor has served on the House Appropriations Committee, the Committee on Standards of Official Conduct, the Education and Labor Committee, and the Committee on Small Business. Currently, in the 111th Congress, Ed serves on the House Appropriations Committee and sits on three subcommittees: the Subcommittee of Energy and Water Development, the Subcommittee on Transportation, Housing and Urban Development, and Related Agencies, and the Subcommittee on Interior, Environment, and Related Agencies. Ed also serves on the Democratic Steering and Policy Committee and is a Chief Deputy Whip in the Democratic Leadership. 
Communist Party support
Arizona Communist Party USA chair Lorenzo Torrez was a pioneer in the struggle for Mexican American political representation. According to fellow party member Steve Valencia. "I always say: Before Ed Pastor and Raul Grijalva, there was Lorenzo Torrez."
Pastor and Grijalva are Arizona's first two Mexican Americans members of the U.S. Congress. But Torrez ran for Congress before they ran, and also boldly ran against Republican Senator Barry Goldwater.
"Lorenzo told us it is time for these majority Latino districts to be represented by a Mexican American," said Valencia. "He wanted voters to see a Latino name on the ballot."
When Pastor declared his candidacy, Torrez rallied the Tucson CP club to join in the effort. Pastor's victory in 1991 set the stage for Grijalva's election in 2002. Ed Pastor and Raul Grijalva both became members of the far left Congressional Progressive Caucus.
Martinez Jobs Bill
In 1994, the Communist Party USA backed Martinez Jobs Bill (HR-4708), was co-sponsored by Democratic Party California Reps Howard Berman, Xavier Becerra, Lucille Roybal-Allard, Robert Scott (Va), Tom Foglietta (Pa), Bennie Thompson (Miss), John Lewis (Ga) and Ed Pastor (Az). Maxine Waters of California was a principal co-sponsor.
