"I don't even want that kind of money, and I don't think I need that kind of money, frankly," Trump said in an interview aired on NBC's "Meet the Press." 

"Look, what we're doing right now, it's like a commercial, except it's tougher than a normal commercial," he said to NBC reporter Hallie Jackson.

Trump, the presumptive GOP presidential nominee, has relied more on free media exposure than traditional advertising.

Research shows he earned nearly $2 billion worth of free media through February. 

But he contends that he has raised "a lot of money" for the Republican Party. 

"We're doing very well," he said, adding he raised "millions of dollars" just last week. 

"[Clinton] is selling herself to Wall Street, and the Wall Street fat cats are putting up a lot of money for her." 

But the self-described "self-funded" candidate's campaign sent an urgent fundraising email to supporters Saturday asking for at least $100,000 in donations by the end of the day to "help get our ads on the air." 

That requested followed a multimillion-dollar ad blitz launched by Clinton, the presumptive Democratic nominee, last week.
