EXCLUSIVE — Americans for Prosperity Action, the Super PAC affiliated with the grassroots network backed by Charles Koch, is spending $5.3 million on a new digital ad campaign boosting Republican candidates in five critical 2026 U.S. Senate races.

The ads first debuted on Wednesday, as Republicans, led by President Donald Trump, gathered in Dallas, Texas, for the party’s first-ever midterm convention. The campaign features 11 ads blanketed across Alaska ($700,000), Iowa ($750,000), Michigan ($1.5 million), New Hampshire ($850,000), and Ohio ($1.5 million) and will run on digital and connected TV platforms.
