Trip Gabriel for the NYT:
One supporter present was Foster Friess, a wealthy investor whose multimillion-dollar donations in 2012 helped Mr. Santorum remain in the race long after he might have quit.
Mr. Friess, in a black cowboy hat, said he would support Mr. Santorum again, but not through a “super PAC,” which reports donors.
“The money I give will be hard to track,” said Mr. Friess, adding that he had spent $26,000 for a private jet to the rally.
Nick Confessore on Twitter: “Consider: a donor says he wants to give money to elect a candidate but will give through groups that claim not to be electing candidates.”
