Pro-voucher billionaire and top Abbott donor called to testify before Texas House committee

Republican megadonor and school-voucher champion Jeff Yass has been called before the Texas House Public Education Committee to explain his millions in recent campaign donations to Texas Gov. Greg Abbott. The Pennsylvania-based billionaire made headlines last December when he dropped a $6 million donation into Abbott's coffers as the Republican governor prepared to push Texas lawmakers to adopt a controversial voucher plan. At the time, Abbott's campaign bragged Yass' contribution amounted to the "largest single donation in Texas history."
