Here's how Trump donors outed by Rep. Joaquin Castro are striking back

Texas donors to President Donald Trump's campaign are banding together to strike back at Rep. Joaquin Castro (D-Texas) after he posted a list that many said was meant to intimidate others from supporting Republicans.

One donor who was targeted told the Washington Examiner that they had branded themselves the "Texas 44," and organized a "fundraising frenzy" to raise money for the president's 2020 reelection campaign.

"My phone's been lit up for two days with calls from many of the Texas 44 and others of our friends here in Texas who are outraged by Castro's comments," said R. H. Bowman, an attorney.

Castro had tweeted the list with a comment many took as a call to harass his supporters.

"Sad to see so many San Antonians as 2019 maximum donors to Donald Trump," Castro tweeted.

While the list is publicly available, it is very unorthodox for an elected official to put out such a list in such a public fashion.

"Their contributions are fueling a campaign of hate that labels Hispanic immigrants as 'invaders,'" Castro added.

Bowman and the "Texas 44" disagree.

"It looks like another million dollars is now headed to support the Trump 2020 campaign from those of us who were targeted," he said, "and other Texans, including Hispanics, incidentally, whose resolve to support [the president] is only strengthened by this personal attack."

Castro's twin brother, Julián Castro, is running for the Democratic presidential nomination.
