“The assertion of executive privilege raises monumental questions,” said Sen. Chuck Grassley of Iowa, ranking Republican on the Senate Judiciary Committee who first began the Fast and Furious investigation.
“How can the president assert executive privilege if there was no White House involvement? How can the president exert executive privilege over documents he’s supposedly never seen? Is something very big being hidden to go to this extreme? The contempt citation is an important procedural mechanism in our system of checks and balances,” he said.
Grassley:
“How can the president exert executive privilege over documents he’s supposedly never seen?”
Bears repeating. Over and over.
