hostile letter threatened García, comparing him to Joseph Stalin and saying that Texans should "drive [him] back to Mexico". In 1953, AGIF published its own study, "What Price Wetbacks", on the issues related to farm labor in South Texas. They invited Senator Lyndon Johnson to speak at their statewide convention. In 1954, attorneys funded by AGIF and LULAC argued and won Hernandez v. Texas in the Supreme Court. The decision, one of the Warren court's first, threw out the plaintiff's murder conviction on the grounds that he had not had a jury of his peers. Court records showed that no one with a Spanish surname had served on a jury in the county for 25 years. In Brown v. Board of Education, the Supreme Court ruled that racial segregation of public schools was unconstitutional. LULAC and AGIF mounted litigation challenges in Texas to ensure that the ruling was applied to gain integrated education for Mexican-American citizens. They took cases to the Texas Supreme Court challenging the practices of independent school districts in Driscoll, Carrizo Springs, and Kingsville. In 1960, Dr. García became national coordinator of the Viva Kennedy Campaign, organized to elect Senator John F. Kennedy as president. García is credited with delivering 85 percent of the Hispanic vote to the Democratic party in that close election. The civil rights agenda of AGIF, however, was not at the forefront of the Kennedy administration's platform. Dr. García and his supporters had to accept his appointment in 1962 as representative of the US in mutual defense treaty talks with the West Indies Federation. The appointment was notable as the first instance that a Mexican American had represented an American President, and talks were successful. After Kennedy was assassinated, Vice-President Lyndon B. Johnson succeeded to the presidency. He appointed García as Presidential Representative, with the rank of Special Ambassador, to the presidential inauguration ceremonies of Dr. Raúl Leoni in Venezuela. In 1966, through the efforts of AGIF and other groups, the state legislature voted to repeal the Texas poll tax, which had been a barrier to voting by poor people. The forum also undertook a march on the Texas state capital to protest the low wages of Mexican agricultural laborers. In 1967, President Johnson appointed Dr. García as alternate representative, with the full rank of Ambassador to the UN. He was tasked with improving US relations with Latin American nations.
