But for some Trump supporters like Ron Wilson, WinRed is a scam artist. Mr. Wilson, an 87-year-old retiree in Illinois, made a series of small contributions last fall that he thought would add up to about $200; by December, federal records show, WinRed and Mr. Trump’s committees had withdrawn more than 70 separate donations from Mr. Wilson worth roughly $2,300.
“Predatory!” Mr. Wilson said of WinRed. Like multiple other donors interviewed, though, he held Mr. Trump himself blameless, telling The Times, “I’m 100 percent loyal to Donald Trump.”
