chuck grassley has been quietly trying to get his ducks in a row for his upcoming hearing on the report, but the stakes for mccabe testifying are differe and quite high, and here's why. earlier this year we reported that mccabe is under criminal investigation here in d.c. based on allegations that he lied to investigators about an inspector general report. he denies any wrongdoing, but any testimony that he denies to congress could be used against him in that separate criminal case. as a result, his lawyer is now asking grassley's committee for a limited immunity deal and it wouldn't pro from all time and it would protect whatever he says in that committee hearing from being used against him in his criminal case. we have no indication that grassley's committee will actually give him such immunity deal and it would require two-thirds vote in the committee and the justice department would have an opportunity to intervene, kate.
