Incoming Senate Majority Leader Harry Reid will miss the state funeral for former President Gerald Ford at the Capitol Rotunda on Saturday night, opting instead to lead a delegation to South America with an expected stop at the Machu Picchu Inca ruins.
Reid, D-Nev., left Wednesday afternoon from Andrews Air Force Base in Maryland with a bipartisan group of five other senators, including Sen. Dick Durbin, D-Ill., the incoming assistant majority leader, for what has been described as a weeklong visit to Bolivia, Ecuador and Peru.
