DHS claims knowledge purchases are authorized

“I am glad that the Inspector Basic agreed to our request to research this doubtlessly unconstitutional abuse of energy by the CBP as a result of we should shield the general public’s Fourth modification rights to be free from warrantless searches,” Warren mentioned.
