Story highlights Trump said he does not know if he would be willing to spend $1 billion of his own money on a general election campaign

People love the fact that I'm putting my own money in," Trump said

Washington (CNN) Donald Trump said the American political process is in need of campaign finance reform, adding that he -- a candidate who has repeatedly touted his decision to self-fund his campaign as a selling point for his candidacy -- hasn't decided if he would accept public financing for the general election.

"I don't know yet. I haven't thought of it. I am thinking about this one," he said. "I'm financing my own campaign. When I get (to the general election), it's a little bit of a different story, because the (Republican Party) gets involved and other people get involved and so a little bit of a different story."

Trump also told CNN's Jake Tapper in an interview that aired Sunday on "State of the Union" that his 2016 rivals, including his top GOP competitor, Texas Sen. Ted Cruz, are beholden to outside interests due to their reliance on donations.

Trump said campaign finance reform is needed "because I think PACs are a horrible thing."

"First of all, everybody is dealing with their PAC. You know, it's supposed to be like this secret thing -- they're all dealing," he said.
