Sources tell CBS News that New Jersey Gov. Chris Christie (R) has told Indiana Gov. Mitch Daniels he would back him in a presidential run, as would Mississippi Gov. Haley Barbour (R) and Wisconsin Gov. Scott Walker (R).
"And as a sign of how important his wife is to the decision, sources tell CBS News that even former First Lady Laura Bush has called Cheri Daniels personally to encourage her to support the effort and offer advice on how to define what her role on the campaign -- and potentially in the White House -- would be."
