Outgoing Secretary of State Hillary Clinton gave a tea party senator an earful during Wednesday’s hearing on the attack on the U.S. embassy in Benghazi, Libya that left a U.S. ambassador dead.

In the heated exchange with Sen. Ron Johnson (R-WI), during which he claimed that U.N. Ambassador Susan Rice “intentionally misled” the American public on what happened in Benghazi, Clinton grew noticeably more frustrated with every passing moment.

As Johnson kept pressing on why the initial statements describing the incident were not completely accurate, Clinton kept insisting that her principle concern was the safety of the embassy staff.
