Senators sent the corresponding letter to Jeffrey Ragsdale, who heads the Department of Professional Responsibility at the Department of Justice.

According to politicians who also rely on the March report of the inspector general of the Ministry of Justice, in 1992 Barr did not properly analyze the surveillance program of the Drug Enforcement Administration, which could have been illegal from the very beginning, and gave permission for its implementation.

“Barra’s permission to this large-scale surveillance program without a minimum legal analysis does not comply with their oath to defend the Constitution and is likely a professional misconduct,” Senator Leahy said in a letter.

According to politicians, Barr “knew or should have known” that neither status law nor federal case law allowed the Drug Enforcement Administration to “collect a total of billions of American telephone conversations.”
