Who'd be asking? That's the Justice Department.
You expect Attorney General Lynch to go before a Grand Jury and ask for this?

And if Hillary wins, it'd be her choice of an Attorney General.
This is a perfect example of where conservatives have screwed up for the past several years. Demanding things they knew wouldn't happen then attacking republicans for not achieving the impossible.
Look at the attacks Trey Gowdy has faced for not putting people in prison for all sorts of scandals while they ignore the fact that the justice department (Obama's Justice Department) is who has the power to bring charges. Trump himself attacked Trey Gowdy for "Letting Clinton get away with it".
Its the same with the endless demands o impeach Obama. It wasn't going to happen because there were never the numbers to convict anyway. That's not the fault of the GOP and its certainly not thefault of every individual senator or representative.
Conservatives need to grow the hell up and stop being so easily distracted and manipulated. In fact, speaking of being distracted and manipulated, the word "Wall" comes to mind.
