Petraeus should testify. Come on, he can't chicken out now; it's his baby. He has to live with what he's done personally to his family but Americans should demand him and Hillary to testify. If Petraeus doesn't on his own terms(he's a coward Imo) or if something happens to him..that's different scenario. Hillary and her crap, that she is traveling is all a set up as usual.

They should not only ‘ask’ them to testify, they should demand it through a subpoena! The House has that power and should use it. Dammit, grow some gonads will you!
