More than two months after Donald Trump skipped a Republican debate to hold a fundraiser for veterans, the targeted beneficiaries are still seeing a fraction of the promised money raised from the Republican’s charitable foundation and his wealthy friends.

A survey by The Wall Street Journal of 19 of the 22 groups originally listed by Mr. Trump’s presidential campaign as the prospective recipients of the funds found that they had received roughly $2.4 million of the estimated $6 million in donations the campaign said the event generated. The total received by all of the groups is likely to be more.

One organization refused to disclose how much it received, another said it needed to submit more paperwork before a check would be forthcoming, and one didn’t respond to multiple inquiries.

All of the groups reported receiving checks from the Donald J. Trump Foundation or associates through the mail, and most arrived in late February in increments of $50,000 or $100,000. Three organizations reported getting smaller donations in March that averaged between $5,000 and $15,000.
