Michigan, afterwards becoming an instructor at the Army School for Personnel Services in Lexington, Virginia. The Army shared Daniel with the United States Marine Corps in 1945, the latter sending him to Sasebo, Nagasaki, Japan to set up a Marine Personnel School. He received "outstanding authority" citations from both branches of service, and was discharged in May 1946. Texas Attorney General Price returned to Texas after his military service and won the seat of Texas Attorney General. As Texas State Attorney General, he argued the 1946 submerged lands ownership lawsuit United States v. California, 332 U.S. 19 before the Supreme Court of the United States in 1947, on behalf of the coastal states. The Supreme Court decided against California on June 23, 1947. Daniel defended the University of Texas law school in the 1950 Sweatt v. Painter desegregation case. Herman Marion Sweatt, a black student, was denied admission to the University of Texas Law School in February 1946. Sweatt had met all the requirements, except that Texas schools were segregated by law. The Supreme Court of the United States ruled in June, 1950, Sweatt must be allowed admission. United States Senate In 1952, Daniel was elected to the United States Senate. He was immediately taken under the wing of Senate Minority Leader Lyndon B. Johnson, with the senior senator helping to alleviate office space shortage by allowing Daniel's staff to work out of LBJ's office. Daniel held positions on committees of the Interior; Interstate and Foreign Commerce; Post Office and Civil Service; and Judiciary, as well as Judiciary subcommittees on Internal Security and Juvenile Delinquency. The new senator worked on a narcotics probe and reforming the electoral college. Opposed to desegregation efforts, Senator Price Daniel joined 19 other senators and 77 members of the United States House of Representatives in signing the 1956 Southern Manifesto, which condemned the 1954 United States Supreme Court decision in Brown v. Board of Education, and encouraged states to resist implementing it. The Supreme Court's 1958 Cooper v. Aaron decision held that the states were bound to uphold the previous decision on desegregation. Tidelands and 1952 elections The most long-lasting accomplishment of Price Daniel was in helping to retain Texas title to the submerged lands, and mineral rights therein, off the coast. The victory has netted billions of dollars for Texas schools. Texas viewed this issue as of primary importance during the 1952 campaign. Eisenhower
