New Mexico Gov. Bill Richardson will hold two fundraisers to help Sen. Hillary Rodham Clinton pay off her presidential campaign debt. Richardson, who was UN ambassador and energy secretary under former President Bill Clinton, drew heat from some of the former first lady's supporters when he endorsed her rival Barack Obama in March during the Democratic presidential primaries. Strategist James Carville compared Richardson to Judas. Several weeks after the endorsement, the former president grew red-faced as he talked to California Democrats at a private meeting about how he expected Richardson to support his wife or at least stay neutral. A spokesman for the governor said the fundraisers are part of the Democratic Party's effort to unify after the hard-fought primary.
