Donald Trump on Tuesday blasted reporters who scrutinized where millions of dollars he claimed to raise for veterans in January went, but about half of the charities who received the donations hadn't been given the funds until last week after a Washington Post report questioned if the money had been distributed. While the majority of the money was raised back in January, about half of the charity groups reached by the Associated Press said the checks were dated May 24 — the same day the presumptive Republican presidential nominee was questioned about the money in a Washington Post interview. The checks were sent via overnight express, the groups said. Trump campaign staffers had declined to release a list of organizations that had benefitted from the January fundraiser for months. On Tuesday, Trump called a press conference to release the names of 41 groups that received a total of $5.6 million in donations, and railed against journalists who had questioned where the money had gone.

"Instead of being like, 'Thank you very much, Mr. Trump,' or 'Trump did a good job,' everyone's saying, 'Who got it? Who got it? Who got it?' and you make me look very bad," Trump said. "I have never received such bad publicity for doing such a good job." The fundraiser was held Jan. 28, the same day and at nearly the same time as Trump's Republican rivals appeared at a Fox News presidential debate. Trump, who at the time was embroiled in a dispute with the network and one of its most popular hosts, Megyn Kelly, refused to attend the debate and hosted the fundraiser instead. Trump said during the fundraiser he had donated $1 million himself to veterans. That donation, made to Marine Corps - Law Enforcement Foundation was not made until May 24, the AP reported. In all, the news agency spoke with 30 of the 41 organizations listed by Trump, and about half of them said they didn't receive a check until last week. The Washington Post's David Fahrenthold had been reaching out to veteran's organizations to find out where the $5.6 million had been donated, including the $1 million donated by Trump himself.

Campaign staffers would not say where the money had been donated, and when Fahrenthold took to Twitter to reach out to organizations to see if they had been beneficiaries, Trump responded.

Amazingly, with all of the money I have raised for the vets, I have got nothing but bad publicity from the dishonest and disgusting media.
