WASHINGTON — When your phone rings during a meeting, it can be embarrassing. It can be even more humiliating when it’s a senator’s phone ringing during a committee hearing. And the ring tone is a song from a Disney animated film. And it’s all caught on TV. During a committee hearing on the merits of a massive free-trade agreement being pushed by the Obama administration, the phone of Sen. Pat Roberts, R-Kansas, went off. The ring tone? “Let It Go,” the ubiquitous hit from Disney’s “Frozen,” The Washington Post reports. Roberts, who was in the midst of grilling Agriculture Secretary Tom Vilsack, looked down at his phone and muttered, “Aw, come on,” before muting the music. Roberts continued, saying to Vilsack, “Just let it go, mister.” “Sorry about that,” he added. He then turned off the phone. “Senator Roberts’s ‘Let it Go’ ringtone is for his grandkids,” his spokeswoman Sarah Little told The Washington Post. “He balances it with Johnny Cash’s ‘I Walk the Line.’ He changes depending on the day.” Roberts didn’t seem to be fazed by the embarrassment. He took to Twitter, looping the song into his comments about the Obama administration.

Somebody had to tell the Obama Administration to “Let it go.” #forthegrandkids — Pat Roberts (@SenPatRoberts) April 16, 2015
