Donald Trump says super PACs are "a big, fat scam."

On "State of the Union" this morning:

TAPPER: You issued a statement this week disavowing all super PACs that are out there in your name, requesting that they return all of the donations and calling on all presidential candidates to do the same. Why?

TRUMP: It's a scam. It's a big, fat scam. These super PACs are a disaster. I have -- I think they said nine or 10 super PACs were set up in my name. I don't even know who these people are. You have all these people raising money, I guess in the name of Trump, that we love Trump. And some of them, I'm sure, do, and probably some of them don't. And I have no idea what they are going to do with the money they are raising. But they are raising all of this money, and they're going to spend it on the campaign. And we have -- you know, the candidates are not supposed to be involved and all this stuff, but they have all this money going. Nobody even knows who the people are. Nobody knows where they are. Nobody knows what they're doing with the money. It's a whole big scam. If you look at Ben Carson, Ben Carson is spending money from super PACs all over the place. Now I hear his super PACs are going to merge. I have heard that his super PACs are essentially running his campaign in Iowa, where they are actually running his campaign, where they are doing all of the ground work and everything. That's not what the purpose of a super PAC was supposed to be. And, by the way, Jeb Bush, the same thing -- he's got one of his best friends that heads up his super PAC. And I'm calling on all candidates to disavow their super PACs. It's a scam. They know it. It's a joke. I mean, it's a joke. They're all laughing about it. I laugh about it. 

It sounds as though Trump, not needing money the way the other candidates do, would like to undercut the power of super PACs to raise money. It's the other candidates who need that money flow.
