Wilson's actions were inappropriate. Truman agreed; Wilson resigned. John R. Steelman, Assistant to the President of the United States (a position which later became the White House Chief of Staff), was named interim director of the Office of Defense Mobilization on March 30. Negotiations between Steelman's staff, employers and the union unraveled over the next seven days, and the union announced it would strike on April 9. In a nationally televised address at 10:30 p.m. Eastern time on April 8, President Truman announced that he was seizing the nation's steel mills under his authority as commander-in-chief. The steelmakers sued to regain control of their property. As the case wound its way through the courts, Putnam attempted to restart negotiations and avoid a strike. On April 23, he personally ordered a $3-per-ton increase in the price of steel. Although the award was higher than the $2.75-per-ton price increase permitted by law, it was lower than the $4.50-per-ton increase last offered to the steelmakers by Arnall 10 days earlier and far lower than the $12-per-ton increase the steelmakers were publicly claiming was needed to make up for the WSB's wage recommendation. An angry Congress began investigating the Truman administration's wage and price stabilization program. Putnam engaged in a public war of words with Wilson after Wilson testified that authority to hear labor disputes should be taken away from ESA, WSB and other stabilization agencies. On June 2, 1952, the U.S. Supreme Court ruled in Youngstown Sheet & Tube Co. v. Sawyer, 343 U.S. 579 (1952) that the president lacked the authority as commander-in-chief to seize the steel mills. The union struck the next day. The strike lasted 53 days. Although Putnam was involved in presidential efforts to resolve the dispute, Truman's personal aides were primarily responsible for intervening in the strike. The steelmakers and the union reached a tentative agreement on July 24, 1952, after Truman threatened to use his powers under the Selective Training and Service Act of 1940 to draft the steelworkers and turn the steel mills into military installations. After just a few hours of negotiations, the parties settled on essentially the same terms offered by the WSB four months earlier. Putnam was outraged by the steel manufacturers' behavior during the steel crisis. He felt the steelmakers had held "a loaded gun poised at the Government's head" and that the employers' publicly stated reasons for forcing the union on
