Another close ally of the Clintons is lending a hand to the super PAC devoted to luring Hillary Clinton into the 2016 presidential race.

Days after James Carville wrote an e-mail on behalf of the group, Ready for Hillary PAC, top Clinton fundraiser and strategist Harold Ickes said he has signed on with the group as an adviser and has reached out to donors on its behalf.

"These are people I know who have told me over the years that they and a lot of other people want her to run," Ickes told the Sunday Times. "They don't have any idea what she's going to do, but if she runs they want to be ready to give whatever assistance they can."

Ickes served as deputy chief of staff to Bill Clinton and was later a top adviser to both Hillary Clinton's 2000 Senate campaign and her 2008 presidential run.
