Sen. Mike Rounds (R-S.D.) on Saturday expressed concern over executive branch handling of classified information in the wake of the Trump indictment while calling prosecution of the former president “inherently political.”

“Regardless of your political position, the news of another indictment against the former president should concern all of us,” Rounds wrote in a statement. “American citizens look to our leaders and our justice system to have integrity – and that integrity is once again being called into question.”

Rounds, who serves on the Senate Armed Services Committee, refrained from naming anyone — including Donald Trump — in his statement, although he said it was “unacceptable” that classified documents have been “treated so carelessly by current and former members of the executive branch,” likely also referencing the retrieval of classified documents from President Joe Biden’s Delaware home and a similar controversy involving former Vice President Mike Pence.
