WASHINGTON -- Senate Armed Services Committee Chairman John McCain (R-Ariz.) on Monday denied reports that Sen. Ted Cruz (R-Texas) is pushing him to hold hearings exploring whether soldiers should be able to carry concealed guns on military bases. “I was fascinated to hear that, since I haven’t heard a thing about it from him, nor has my staff heard from his staff,” McCain told reporters. Responding to a question about a Politico report that Cruz said he is “pressing” for a hearing on easing the gun ban for soldiers, McCain said, “I have not a clue.” Cruz, a 2016 presidential contender seeking distance himself from the rest of the Republican field, said Sunday he is pressuring McCain directly to hold the hearing.
