Senator Pat Roberts' Cell Phone Blares Frozen -

U.S. senator and doting grandfather Pat Roberts was in a Disney mood on Thursday, apparently. His cell phone rang loudly during a Senate Finance Committee meeting, interrupting speaker Agriculture Secretary Tom Vilsack. His ringtone? Frozen's "Let it Go." The blaring vocals by Idina Menzel were picked up by his table microphone, spurring scores of attendees to chuckle and Vilsack to crack a smile, as seen in videos posted by CNBC a NBC News' House of Representatives producer.
