His tweet came after Warren accused Trump on Tuesday of profiting off of the 2008 housing market crash.

“Donald Trump was drooling over the idea of a housing meltdown, because it meant that he could buy up a bunch more property on the cheap,” she said at the Center for Popular Democracy’s annual gala in Washington, D.C.

“What kind of man does that? Root for people to get thrown out on the street? Root for people to lose their jobs? Root for people to lose their pensions?”

Trump’s response references reports claiming that Warren potentially benefited from a housing crisis herself.

Reports emerged during Warren’s Senate campaign in 2012 that she profited off her native Oklahoma City’s volatile market in the 1990s.

Warren reportedly loaned money at high interest rates to relatives and purchased foreclosed properties at bargain prices. The Boston Herald reported that Warren took part in about 12 Oklahoma real estate deals.

Warren's office on Wednesday said there was nothing wrong with those transactions.

"Senator Warren and her husband Bruce are fortunate to be in a position where they have been able to help relatives buy their homes and in some cases make a living by fixing up houses and managing rental properties," Warren press secretary Lacey J. Rose said in a statement.

The Warren-Trump fight comes as the presumptive GOP nominee faces criticism for statements he made saying he hoped for a market crash two years before the housing bubble burst in 2008.

“I sort of hope that happens because then people like me would go in and buy,” he said in a 2006 audiobook from Trump University, which resurfaced last week.

“If there is a bubble burst, as they call it, you know, you could make a lot of money,” the billionaire added. "At the same time, I don’t think that will happen.”

“He actually said he was hoping for the crash that caused hard-working families in California and across America to lose their jobs,” she said during a campaign event outside Los Angeles.

“All because he thought he could take advantage of it to make some money for himself."
