LANSDOWNE, Va. ‹ Charles Colson, a Richard Nixon White House operative during the Watergate scandal who had a reputation for ruthlessness before going to jail and starting a prison ministry, died on Saturday at age 80, the ministry said.

Colson, who compiled Nixon's infamous "enemies list" before Watergate brought down the president in 1974, died of complications from a brain hemorrhage after being admitted to a hospital in Fairfax on March 31, Prison Fellowship Ministries said in a statement on its website.
