Problem: Dwight D. Eisenhower:

In May 1955, McCarthy threatened to issue subpoenas to White House personnel. Eisenhower was furious, and issued an order as follows: "It is essential to efficient and effective administration that employees of the Executive Branch be in a position to be completely candid in advising with each other on official matters ... it is not in the public interest that any of their conversations or communications, or any documents or reproductions, concerning such advice be disclosed." This was an unprecedented step by Eisenhower to protect communication beyond the confines of a cabinet meeting, and soon became a tradition known as executive privilege. Ike's denial of McCarthy's access to his staff reduced McCarthy's hearings to rants about trivial matters, and contributed to his ultimate downfall.

Problem: Dwight D. Eisenhower:

In 1957, the state of Arkansas refused to honor a federal court order to integrate their public school system stemming from the Brown decision. Eisenhower demanded that Arkansas governor Orval Faubus obey the court order. When Faubus balked, the president placed the Arkansas National Guard under federal control and sent in the 101st Airborne Division. They escorted and protected nine black students' entry to Little Rock Central High School, an all-white public school, for the first time since the Reconstruction Era. Martin Luther King Jr. wrote to Eisenhower to thank him for his actions, writing "The overwhelming majority of southerners, Negro and white, stand firmly behind your resolute action to restore law and order in Little Rock".
