Fifty years ago, five men were arrested after breaking into the Washington headquarters of the Democratic National Committee.

The ensuing scandal would eventually lead to the resignation of President Richard Nixon and become a synonym for government corruption.

A CNN original series, "Watergate: Blueprint for a Scandal," reexamined the infamous break-in and cover-up — this time told firsthand by John Dean, former White House counsel.

Police check out the Democratic National Committee's headquarters in Washington on June 17, 1972. Five men were arrested early that morning after a break-in at the headquarters, which was inside the Watergate office building.
