GOP presidential front-runner Mitt Romney said he won't rule out former Pennsylvania Sen. Rick Santorum as a vice presidential running mate. In fact, he said he won't rule out anyone at this point.
The former Massachusetts governor said he doesn't have a list of possible candidates, but he added that he would certainly consider the people who were once his opponents.
Romney said the first criterion is whether or not the person could be the president if necessary.
"I think you'll see us all come together in a very powerful way," Romney told Fox News Wednesday. "The time for that will happen down the road as we spend more time together, hit the trail together."
Santorum dropped out of the race for the White House on Tuesday, citing health concerns for his daughter, Bella.
Already, some of the former lawmaker's donors have announced their intentions to back Romney. Hours after the news of Santorum's exit, Foster Friess, the Wyoming investor who donated $1.7 million to the Santorum Super PAC, said he was shifting his support to Romney.
"I'm obviously going to be of help in whatever way I can," Friess said.
