Justice Department officials advised an advocacy group to cancel an event on gender diversity featuring former U.S. Attorney for D.C. Jessie Liu over a new executive order from President Donald Trump against federal trainings that suggest gender biases exist in the workplace, leaders of that group said Friday.

In an email to members Friday afternoon, DOJ Gender Equality Network leaders said officials at the department’s Justice Management Division, which provides employees with guidance on DOJ policies, on Thursday “advised DOJ GEN that we must cancel” the event in light of Trump’s executive order.
