Trey Gowdy has requested permission from the White House to grant him the necessary conditions so that he would be able to do his job well. However, that permission has been denied for 5 years.
The biggest obstacle that his job as congressional investigator presents is security clearance. And Trey Gowdy is no stranger to the issue of security clearance since he has found himself in multiple situations when he had to investigate people who held titles like “Secretary of State” and “Special Aide to the President” or even “President”.
The good old line that “It’s a matter of national security” has served as the best excuse for Hillary Clinton and her people to keep Gowdy from doing his work. This is always a good answer when you don’t have any actual reason.
