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.
What did McCarthy threaten to do in May of 1955?

Beginning with the Paris Exposition of 1878, the instrument's popularity rebounded. The Exposition was one of many stops for a popular new performing group the Estudiantes Españoles (Spanish Students). They danced and played guitars, violins and the bandurria, which became confused with the mandolin. Along with the energy and awareness created by the day's hit sensation, a wave of Italian mandolinists travelled Europe in the 1880s and 1890s and in the United States by the mid-1880s, playing and teaching their instrument. The instrument's popularity continued to increase during the 1890s and mandolin popularity was at its height in "early years of the 20th century." Thousands were taking up the instrument as a pastime, and it became an instrument of society, taken up by young men and women. Mandolin orchestras were formed worldwide, incorporating not only the mandolin family of instruments, but also guitars, double basses and zithers.
