Joe Stephens reports in this morning's Washington Post on a practice we wondered about a while back: members of Congress who sponsor "temporary duty suspensions" -- cuts in the taxes assessed on a specific imported item. (Thomas, the Library of Congress's online tool for tracking legislation, lists hundreds of them when you search for the phrase, "temporary suspension of duty.") Each tariff suspension can cost the Treasury as much as $500,000--that is, it's a $500,000 tax break targeted to some special interest that asked for the tariff suspension.
