President Donald Trump signed a directive Wednesday removing the security clearances of University of Pennsylvania community members, the latest government action to pummel the president’s alma mater.

In the directive, Trump, a 1968 Wharton School of Business graduate, ordered the Department of Justice to investigate Miles Taylor, a former senior Department of Homeland Security official who has criticized the president, including in a 2018 New York Times op-ed and in a book in which he alleges presidential misconduct during Trump’s first term.

Taylor taught an undergraduate course at Penn in fall 2023 called The Future of Conservatism and the GOP, according to The Daily Pennsylvanian, and it’s this tie that has put Penn in the crosshairs.

Trump’s memo asks the attorney general, the director of national intelligence and other relevant department and agency heads to suspend the security clearances held by Taylor “and any individuals at entities associated with Taylor, including the University of Pennsylvania.”

According to The Philadelphia Inquirer, Penn does not conduct classified research and has no security clearance.

“The University does not possess a government security clearance and cannot as a corporate entity possess classified material,” the website states. “It is the policy of the university not to accept agreements which require access to classified data, require university employees to obtain security clearances, or restrict the dissemination of the results.”

Penn is also currently facing a $175 million funding freeze from the federal government, announced in March, related to participation of a transgender athlete on the women’s swimming team in 2022. The university was further affected by visa revocations of international students and scholars earlier this week.
