In a six-figure radio ad being released in Georgia today, Donald Trump Jr. tells the state’s voters that the U.S. Senate — and his father’s accomplishments — are on the line during January’s special election, according to audio obtained by Axios.

Why it matters: Trump Jr.’s first of many advertisements in the Georgia Senate races argues the race isn’t just about electing the Republican incumbents, but also about preserving President Trump’s agenda.

Details: The one-minute radio ad is sponsored by a new super PAC, Save the U.S. Senate, which was recently formed by advisers to Trump Jr. amid growing concerns that Trump voters will boycott the Georgia Senate runoffs.
