Yes.  This actually happened.  CNN’s Piers Morgan interviewed Sen. Bernie Sanders (D) VA, on the NSA/ PRISM data mining scandal.  He was notably unimpressed with the president on the issue.

via MrConservative:

Morgan quoted a recent New York Times editorial that said the Obama administration has “now lost all credibility on this issue.”

Socialist Senator Bernie Sanders was on the show as his guest. Morgan asked the senator from Vermont if he thought Obama’s surveillance decisions are “worse than anything George W. Bush did.”

Perhaps there’s an actual thinking brain in there after all.
