On the urging of local political leaders of Pampanga province, President Quirino recalled Macapagal from his position in Washington to run for a seat in the House of Representatives representing the 1st District of Pampanga. The district's incumbent, Representative Amado Yuzon, was a friend of Macapagal, but was opposed by the administration due to his support by communist groups. After a campaign that Macapagal described as cordial and free of personal attacks, he won a landslide victory in the 1949 election. He won re-election in the 1953 election, and served as Representative in the 2nd and 3rd Congress. At the start of legislative sessions in 1950, the members of the House of Representatives elected Macapagal as Chairman of the Committee on Foreign Affairs, and he was given several important foreign assignments. He was a Philippine delegate to the United Nations General Assembly multiple times, notably distinguishing himself in debates over Communist aggression with Andrei Vishinsky and Jacob Malik of the Soviet Union. He took part in negotiations for the U.S.-R.P. Mutual Defense Treaty, the Laurel-Langley Agreement, and the Japanese Peace Treaty. He also authored the Foreign Service Act, which reorganized and strengthened the Philippine foreign service. As a Representative, Macapagal authored and sponsored several laws of socio-economic importance, particularly aimed at benefiting the rural areas and the poor. Among the pieces of legislation which Macapagal promoted were the Minimum Wage Law, Rural Health Law, Rural Bank Law, the Law on Barrio Councils, the Barrio Industrialization Law, and a law nationalizing the rice and corn industries.
