President Donald Trump fired off at Maryland Governor Wes Moore (D) early morning Thursday following reports that the governor had mistakenly listed himself as a Bronze Star recipient in an application nearly two decades ago.

Moore and Trump have feuded publicly over the past week after Trump, following the federal takeover of Washington, D.C., threatened to send the National Guard and federal officers to Maryland’s capital city, Baltimore. Moore, citing Baltimore’s shrinking crime rate, invited Trump to “walk the streets of Maryland” with him to see the improvements in person, though Trump declined the offer.

Now, Trump is seizing on old reporting from The Hill that details what Moore admitted to being an “honest mistake.”

“But is that the end of his political career,” wrote Trump early morning Thursday on his social media platform Truth Social. “He was very disrespectful to the Office of the President!”

According to The New York Times, Moore had applied to a White House Fellowship in 2006 following his almost 20 years in the Army Reserve, and listed himself as being a Bronze Star recipient, despite never having been awarded the decoration.

In a statement on Thursday, Moore said he listed the Bronze Star at the urging of his deputy brigade commander, who advised him to include it on the application and assured him that senior officers had already approved the award, a story that was corroborated with to the New York Times by Lt. Gen. Michael Fenzel, described as a mentor to Moore.
