Democratic Texas congressman Joaquin Castro's published list of Trump donors in his hometown of San Antonio also included at least two people who have contributed to him, a Washington Free Beacon review found.
Castro on Monday published the names and employers of 44 people who've contributed to Trump, accusing them of "fueling a campaign of hate" against the Hispanic community with their contributions. Two of the named donors have in the past contributed substantial sums to Castro's political campaigns.
One of them is William Greehey, a San Antonio energy executive who contributed at least $10,000 to Castro during his first two campaigns in 2011 and 2013, according to Federal Election Commission records.
Greehey was targeted by Castro for contributing $5,600 to Trump this April.
Also included on Castro's list was Wayne Harwell, who gave $1,000 to Castro in 2011 and has also contributed to Trump.
Harwell told Fox News he has no intentions to contribute to Castro ever again.
"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 said. "Obviously Castro feels pretty strongly against me."
Attempts to reach Greehey through his philanthropic foundation and NuStar Energy, where he is a top executive, were unsuccessful.
Castro has kept his list of Trump supporters in San Antonio up despite calls from the Trump campaign, which described it as a "target list," to take it down.
Castro went on MSNBC Wednesday morning to defend his decision to publish names of private citizens and target their businesses.
"What I want is for people to think twice about supporting a guy who is fueling hate in this country," Castro said. He also attempted to distance himself from the list, saying his team wasn't responsible for creating it.
"This was already circulating, I shared it, I didn't create the graphic," Castro said.
The Trump campaign called it "harassment."
"At the very least [Castro] is inviting harassment of these private citizens," said Tim Murtaugh, the campaign's director of communications. "At worst, he's encouraging violence."
