President Biden has mandated workplace race-based diversity training programs in all federal agencies — controversial courses that were previously banned as divisive by former President Trump.

In an executive order issued Friday, Biden directed all federal agencies to school their employees on “systemic and institutional racism” and “implicit and unconscious bias” — buzzwords associated with critical race theory, whose proponents see racism as the foundation of American society.

“These types of trainings equip public servants to best serve the American public, and the many diverse communities that make American strong,” the White House claimed in a Friday evening statement.

President Trump nixed such training programs in September, declaring them to be “divisive, un-American propaganda.”

Biden, in one of his first acts after taking the oath of office, rescinded Trump’s ban — but did not, until now, require the trainings to be implemented.

Biden’s order came just three days after Vice President Kamala Harris broke a party-line Senate deadlock to confirm Kiran Ahuja, who has ties to critical race theory, as director of the federal Office of Personnel Management, overcoming Republican efforts to sink the nomination.

Ahuja’s connection to the subject comes via her nonprofit organization Philanthropy Northwest, which hosted CRT activist Ibram X. Kendi at an event, Fox News reported.

On Wednesday, Gen. Mark Milley, chairman of the Pentagon’s Joint Chiefs of Staff, defended the theory’s use in the West Point curriculum during a budget hearing of the House Armed Services Committee.
