Mark Cuban isn’t buying Donald Trump’s claim that he could self-fund his presidential campaign if he needed to.

“If @realDonaldTrump were fractionally as rich as he says he is, he would write a$200mm check to propel his campaign,” the billionaire entrepreneur and Dallas Mavericks owner wrote Tuesday on Twitter. “He doesn't have the cash.”


Cuban’s comments followed Trump’s media offensive Tuesday, punching back against a Federal Election Commission report showing his campaign had just $1.3 million in cash on hand at the beginning of June. Hillary Clinton’s campaign, by comparison, boasted a war chest filled with $42 million at the beginning of the month.

It’s not the first time that Cuban has been critical of Trump’s financial claims. The “Shark Tank” judge publicly doubted Trump’s stated net worth of $10 billion, and later predicted that the real estate mogul would “have to grovel” for cash from political donors. He has also attacked Trump’s myriad business interests and has indicated he’d be open to running as Hillary Clinton’s vice presidential pick, a ticket Democratic insiders have deemed unlikely.

Trump boasted in separate interviews on Fox News’ “Fox & Friends" and NBC’s “Today” that his paltry campaign fundraising operation wasn’t paltry at all. He said he raised $12 million for the Republican Party over the weekend on the campaign trail in Texas, Nevada and Arizona but complained that while much of the GOP has backed him, the refusal by some Republicans to get in line has hurt his wallet.

Even without a unified party behind him, Trump said he could easily infuse his own money into the general election campaign, the claim that Cuban found dubious.

"I have a lot of cash and I can do like I did with the other,” Trump said, referring to his primary bid. “Just spend money on myself and go happily along, and I think I win that way.”
