If they do invite her back to testify, any repubs who questioned her before, should not be there this time. Hillary was allowed to verbally walk all over the questioning parties last time. Too easily intimidated.
Jim Jordan should be there, with his tough guy game face, but maybe not Daryl Issa. Nothing reaches a conclusion with Issa.
She testified before the senate not the House before. Issa had nothing to do with that.
