FILE - Sen. Howard Baker, R-Tenn., vice chairman of the Senate Watergate Investigating Committee, questions witness James McCord during hearing in Washington, on May 18, 1973. The traumas of Watergate and Jan. 6 are a half century apart, in vastly different eras, and they were about different things. But in both episodes, a president tried to do an end run around democracy. Friday is the 50th anniversary of the Watergate break-in that eventually consumed Richard Nixon's presidency. (AP Photo)
