Lewis Strauss
After Dwight Eisenhower became president, Lewis Strauss called J. Edgar Hoover and told him that Robert Oppenheimer was a Communist.  The FBI then tried to decide if Oppenheimer were a spy for the Soviet Union.  Many of Oppenheimer’s friends said that Strauss was unfair to Oppenheimer.  President Eisenhower wanted to make Strauss the Secretary of Commerce but the US Senate did not approve of this choice. One of the reasons was because people were angry about Oppenheimer.
