Lots of standard Sunday fare this morning — Mike Rogers and Jane Harman on Syria and the Tsarnaevs, McCain and Durbin on immigration reform — with two noteworthy exceptions. Darrell Issa will appear on CBS to preview the new round of hearings with Benghazi whistleblowers, whose star witnesses have just been revealed. And Jim DeMint will be on ABC to explain the Heritage Foundation’s opposition to the new amnesty bill and whether he’s disappointed in his former protege, Marco Rubio, for almost single-handedly making it happen.
