Hector Rodriquez has become the first Hispanic candidate to enter the crowded field seeking the Democratic nomination for an at-large seat in the D.C. City Council.

Rodriquez announced his candiacy Saturday on the steps of the District Building. A Washington resident for 12 years, Rodriquez is a member of the D.C. Latino Community Development Commission.

He pointed to his service on a number of task forces and committees formed to bring about better living conditions and employment opportunities for all disadvantaged groups. In 1974, he was vice chairman of the D.C. Home Rule Committee.

Active in Democratic politics for many years, he worked in the Carter-Mondale campaign of 1976. He also aided campaigns of the late Sen. Hubert H. Humphery (D-Minn.).

Rodriquez is the sixth entrant in the primary race to fill the seat on the council being vacated by Marion Barry (D-At Large), a candidate for mayor.

Rodriquez announced a 20-point legislative program that includes the enactment of a D.C. full-employment bill patterned after the Humphery-Hawkins bill.

Rodriquez also has proposed steps to increase the city's housing supply and to promote multilingual education. He said he would explore the conversion of the National Visitor Center (the former Union Station building) into a convention center. He established headquarters at 913 U St. NW.
