WASHINGTON (AP) — The Trump administration on Thursday opened a civil rights investigation into the hiring practices at George Mason University, expanding a national campaign against diversity policies to Virginia’s largest public university.

The Department of Education launched a Title VI investigation Thursday into George Mason University for allegedly illegally using race and other “immutable characteristics” in the school’s policies and personnel decisions.

The U.S. government on Thursday announced probes into hiring practices and diversity, equity and inclusion initiatives by the state of Minnesota and Virginia's George Mason University. It was the latest crackdown on such programs by President Donald Trump's administration.
