Chester Plummer was a taxi driver in the Washington, D.C. area of the United States who attempted to invade the White House.
On July 27, 1976, Plummer scaled the White House fence, armed with a piece of pipe. While advancing towards the White House, he was ordered to stop by a Secret Service officer. Upon Plummer's refusal, he was shot and killed by the officer. It is unknown whether Plummer intended to attack President Gerald Ford or had another motive.[1]
