Santorum campaign reports $2 million fundraising haul

Rick Santorum's campaign says it has raised $2 million over the last week.

"@RickSantorum has raised more than 2million since Tuesday night #gameon," Santorum campaign manager Michael Biundo tweeted Friday.

The campaign has reported an influx of donations since Santorum's victories in three Republican presidential primary contests on Tuesday: in Colorado, Minnesota and Missouri. 

Foster Friess, the top donor for the pro-Santorum Red, White and Blue Fund super-PAC, said Thursday that it had received a $1 million donation this week as well. Friess would not say who the donor was.
