Senate Majority Leader Harry Reid, D-Nev., has not endorsed a Democratic presidential candidate, but his son has.

Rory Reid is signing on as Nevada chairman for Sen. Hillary Rodham Clinton's presidential bid. He will be senior adviser on Western issues including public lands, transportation, resources and conservation, growth and affordable housing, the New York senator's campaign said in a statement Sunday.

Reid, 44, is chairman of the Clark County, Nev., Commission and a former chairman of the Nevada State Democratic Party.

He was elected Clark County commissioner in 2002 and was re-elected last fall. His colleagues appointed him chairman in 2005 and again in January.
