Texas Democrat Representative Joaquin Castro tried to shame Trump donors by publishing their information. The information is public, but this move was at the least, distasteful.

The move backfired however when Castro revealed the name of one of his donors who also donated to the president.

According to Fox News:

EXCLUSIVE: Trump donors whose names and employers were posted in a highly controversial tweet by Democratic Rep. Joaquin Castro blasted the Texas congressman on Wednesday for what they described as a “ridiculous” stunt and, in interviews with Fox News, rejected his claim that they are “fueling a campaign of hate” against Hispanics.

One of those Trump donors even revealed he’s also been a supporter of local Democratic lawmakers—including Castro himself.

Wayne Harwell, the owner of a local real estate development company whose name appeared on the list Castro shared on Monday night, told Fox News in a phone interview that he donated money to Castro’s congressional campaign. But he suggested that after Castro outed him in a bid to shame Trump supporters, he won’t be supporting Castro anymore.

“I was also on a list of people that gave to Castro and if he dislikes me enough that he wants to put my name out there against Trump, I’m not going to give money to him,” Harwell told Fox News. “Obviously Castro feels pretty strongly against me.”

Harwell explained that he is an independent but is also a supporter of Trump. It looks like Republicans can thank Castro for alienating another Democrat donor.
