Gov. Chris Christie (R) stepped up his criticism of Sen. Rand Paul (R-KY), telling MSNBC the Kentucky senator should be made to testify before Congress in the event of a future terrorist attack because his opposition to NSA data collection has made the country “weaker and more vulnerable.” Said Christie: “He should be in hearings in front of Congress if there’s another attack, not the director of the FBI or the director of the CIA.”
