Secretary of State John Kerry said Tuesday that the several investigations into Hillary Clinton's private email system has significantly tied up the State Department over the last year, despite the more than $2 million Congress gave State to deal with it. "We have more than 50 ... simultaneous investigations going on, and we have an unprecedented number of FOIA requests," Kerry told the Senate Foreign Relations Committee. "I have had to cannibalize bureaus to get people to go spend their time on these requests." "I'm concerned about it because this is tying up international diplomats," he said.
