The head of the most prominent teachers' union in the United States raked in more than $500,000 in pay as the group showered liberal causes with money and fought to keep schools closed during the pandemic, tax forms provided to Fox News Digital show.

Becky Pringle, president of the National Education Association (NEA), the country's largest teachers' union, pocketed $534,243 in compensation from the NEA and its related organizations between September 2020 and August 2021, an increase of $25,000 from the previous calendar year, newest tax forms show.

"Becky Pringle lined her pockets with over half a million dollars and peddled politics at the expense of returning to in-person learning," said Caitland Sutherland, executive director of Americans for Public Trust, who provided the tax forms to Fox News Digital.
