Iowa Sen. Joni Ernst used her speech before the Republican National Convention to attack former Secretary of State Hillary Clinton over her foreign policy credentials and prop up Donald Trump’s in a speech designed to showcase America’s military might on Monday night.

Flanked by members of the U.S. Armed Forces, Ernst used her perch as a rising star within the party to hit Clinton for her failures as secretary of state, particularly her inability in stopping terrorism and the Islamic State. Her speech was the second to last of the evening, forcing her to deliver it to a crowd that had thinned out significantly after Melania Trump delivered her address during the 10 p.m. hour.
