The Maryland State Police Department is investigating an anti-crime event, which the department titled “Make Waldorf Great Again.”

The event is a riff on former President Donald Trump’s “Make America Great Again” slogan, which many have associated with extremist groups purporting a white nationalist and racist agenda.

Sources told Fox 5 — which was first to report the news — that Black officers took offense to the event’s name. In an email to DCist/WAMU, Maryland State Police spokesperson Greg Shipley wrote the issue was brought forth by state troopers, but he could not confirm their race.

“Make Waldorf Great Again,” was held Tuesday in Waldorf, Shipley wrote. It was reportedly geared toward reducing traffic violations and other crimes.

Shipley confirmed Thursday that the department has opened an investigation into the event.

“After being made aware of that [event] yesterday afternoon, Lt. Colonel Roland Butler, Chief of the Field Operations Bureau, ordered an immediate investigation by the Internal Affairs Division into this issue,” Shipley wrote in an email.

Shipley writes that the county police department is “concerned about the perceptions that could have been created” by the event’s name.

More than 50% of Waldorf’s population is Black or African American, according to the Census Bureau.

Maryland, like states across the country, is grappling with pervasive racism within the ranks of its police department. An unredacted copy of an investigation into the Prince George’s County Police Department released this week found allegations of racial discrimination, an inadequate system for filing complaints against officers, and a failure by leadership to discipline officers for racial profiling.

Last month, Maryland State Police troopers accused the department of racism and discrimination in hiring practices, disparities in disciplinary actions, and alleged instances of retaliation. The agency has denied the allegations.
