 And Madam Secretary, the great state of Iowa proudly casts all of its 40 votes for President Donald J. Trump. Iowa Attorney General Brenna Byrd was elected a temporary chair of the convention and nominated Trump's running mate, Ohio Senator J.D. Vance. Byrd also is set to speak at the convention tomorrow. It's been another day in the broiler with heat indices in the triple digits today and excessive heat warning remains in place for parts of southwest Iowa until 8 tonight.
