U.S. senators are "Frozen" fans, too.

A Senate Finance Committee meeting got an unexpected interruption from a “Let it Go” ringtone on Thursday.

Pat Roberts got a call during a meeting on U.S. Tariff Policy, and the song made popular by Disney’s hit animated feature film began playing on his cellphone.

“Aw, come on,” the senior senator from Kansas said.

After some laughs from people in the room, the 78-year-old said, “Just let it go."

Roberts' office released a statement about the incident.

"Senator Roberts' 'Let it Go' ringtone is for his grandkids. He balances it with Johnny Cash's ‘I Walk the Line’. He changes depending on the day,” his spokeswoman Sarah Little said in a statement.
