One of the Republican Party’s biggest donors — a tech and financial industry oligarch who’s been called Pennsylvania’s version of Elon Musk — is the top beneficiary of a state tax loophole that allows the wealthy to write off billions in donations to private and religious schools, even as the Keystone State’s public school system has faltered.

As that tax loophole has been broadened over the past few years, the billionaire Donald Trump supporter — Jeffrey Yass — has doled out tens of millions to elect state legislators who were involved in these policy decisions.

The findings come from a new report by the public policy institute Action Center on Race and the Economy, the corporate watchdog group LittleSis, and the All Eyes on Yass Campaign provided exclusively to the Lever, detailing how over the course of nearly twenty years, the Pennsylvania legislature has funneled more than $2.5 billion into private and religious schools by allowing wealthy people and businesses to donate to these schools’ tuition scholarships and then write off 90 percent of those expenses as tax credits.
