Richardson's shot at Bill

From NBC's Domenico Montanaro
Bill Richardson took a bit of a swipe at Bill Clinton after Hillary Clinton's rousing speech.

She was "sending a signal to her supporters -- and maybe her husband -- that they should go all out for Barack Obama," Richardson told NBC's David Gregory from the convention floor.

There was friction between Clinton and Richardson during the primary season after Richardson, who served in the Clinton cabinet, came out in support of Obama. Richardson even watched the Super Bowl with Bill Clinton -- as the former president was courting his support. When Richardson threw his support to Obama, former Clinton adviser James Carville went so far as to call the New Mexico governor, "Judas."

NBC News has confirmed that Hillary Clinton will be at Obama's Invesco speech. Bill Clinton's plans, however, remain unclear.
