Darrell Issa is like a rabid dog who bites down and won't let go. His investigation into Benghazi has cost millions of taxpayer dollars and has revealed nothing. It is a witch hunt that has no witch. A recently discovered White House email (that contains nothing we didn't already know) is being called a "smoking gun" by the GOP. The only thing smoking here is the huge pile of money they are burning to investigate this non-existent scandal.
