Gov. Greg Abbott received a $6 million campaign contribution last month, which his campaign is calling the “largest single donation in Texas history.” The check came from Jeff Yass, a national Republican megadonor whose priority issues include school vouchers. Abbott spent 2023 unsuccessfully pushing for a voucher program and is now targeting state House Republicans in the March primary who thwarted his agenda. Abbott accepted the $6 million donation — dated Dec. 18 — in a little-used account, suggesting he was setting it aside from funds raised for his reelection campaign. Yass is a billionaire from Pennsylvania who is co-founder and managing director of the Philadelphia-based investment firm Susquehanna International Group. He is also a top proponent of “school choice,” or programs that allow parents to use taxpayer dollars to subsidize private school costs.

When it comes to politics, Yass has also been a multimillion-dollar donor to the Club for Growth, the national anti-tax group that has boosted Texas Republicans like U.S. Sen. Ted Cruz and U.S. Rep. Chip Roy of Austin.
