Trump said Wednesday he'll be making a decision soon on whether to embrace the support of super-PACs in the general election after proudly touting a self-funded primary campaign.

"I'm going to be making a decision over the next week," Trump said. "I do love self-funding, and I don't want anything for myself, but we do need money for the party."

"Do I want to sell a couple of buildings and self-fund? I don't know that I want to do that necessarily, but I really won't be asking for money for myself, I'll be asking for money for the party," he said.

The businessman also showed little interest in shedding the controversial proposals or rhetoric that have accompanied his rise to the top of the Republican field, calling columnist George Will "a major loser" and "a dour guy."

"I find him to be a very boring person and dull," Trump said of the columnist, who has sharply criticized his campaign. "He's a very nasty guy."

Trump indicated he'd stand by his proposal from December to bar Muslims from entering the United States: "Yes, we have to find out what the hell is going on."

The outspoken businessman also denied the theory that women would not support him in the general election when an MSNBC panelist argued female voters want more consistency in a president.

"Actually, I don't shoot from the hip," Trump said, before touting his support among men compared to Clinton. "That's her weakness."
