President Trump on Thursday is set to sign an executive order on campus free speech, ordering colleges to “support free speech” or face “very costly” consequences.

An administration official said the order — part of the president’s crusade against “political correctness” — basically reinforces what most schools are already supposed to be doing by mandating that they agree to promote free speech or risk losing billions in federal research funding.

“While many schools — or all schools — are frankly supposed to follow this currently, it will ensure that grant dollars are associated through the grant-making process, and schools will have to certify that they’re following this condition,” the official said, according to Politico.

The order will tell 12 federal agencies that fund university research to add language to existing agreements the colleges have to sign to get the cash.

Public universities will have to vow to uphold the First Amendment — something they already must do — and private universities will have to promise to “comply with their stated institutional policies regarding free inquiry,” essentially setting their own rules, the official said.

In addition, the order would require the Education Department to publish information on earnings, debt, default rates and loan repayment rates to its college “scorecard” and submit policy recommendations to the president about institutions sharing the financial risk of student loans.
