Rep. Joaquin Castro’s effort to shame and embarrass constituents who donated the maximum amount to President Trump’s reelection bid has dredged up records showing that at least six also gave to the Texas congressman and his twin brother, Democratic presidential candidate Julián Castro.

Joaquin Castro on Monday drew a torrent of criticism when the Twitter account operated by his reelection campaign listed 44 residents of San Antonio who donated the maximum amount to President Trump’s campaign for reelection so far this year.

“Sad to see so many San Antonians as 2019 maximum donors to Donald Trump — the owner of ⁦@BillMillerBarBQ⁩, owner of the ⁦@HistoricPearl, realtor Phyllis Browning, etc⁩.” the Monday tweet said. “Their contributions are fueling a campaign of hate that labels Hispanic immigrants as ‘invaders.'”
