ATLANTA — Donald Trump Jr. released an ad Thursday calling on Georgians to defend President Donald Trump’s accomplishments by preserving the Senate Republican majority.

“The radical left wants to tear down everything we’ve accomplished — defunding the police, eliminating private health insurance, and dismantling the Supreme Court,” Trump Jr. says in the ad. “On January 5, the U.S. Senate is on the line, and my father’s accomplishments are on your ballot. Don’t let them take Georgia.”

The Save the U.S. Senate PAC, a group founded by Trump Jr. aides Taylor Budowich and Andy Surabian, will run the $500,000 ad campaign. The ad campaign will run on conservative cable and digital channels.

President Donald Trump and Trump Jr. have urged Georgians to vote in the January Senate runoffs. The Senate runoffs to reelect Sens. Kelly Loeffler (R-GA) and David Perdue (R-GA) play a pivotal role in the battle for the Senate majority. If Loeffler and Perdue lose their Senate races, then Sen. Kamala Harris (D-CA), the likely next vice president, becomes the Senate’s tiebreaking vote.

This would give a Democrat-controlled Congress significant latitude to try to undo Trump’s legacy.

Budowich said on Tuesday, “Trump supporters in Georgia must hold the line. If Jon Ossoff and Raphael Warnock win, their socialist policies will destroy this nation. Protecting the president’s accomplishments and saving America will be decided by the voters of Georgia.”

Democrats have invested significant resources to flip the Senate blue by ousting Loeffler and Perdue.

House Speaker Nancy Pelosi (D-CA) held a high-priced fundraiser for Georgia Senate Democrats Raphael Warnock and Jon Ossoff.

Sen. Elizabeth Warren (D-MA), who supports the Green New Deal and Medicare for All, will hold a fundraiser for Ossoff on Tuesday evening.
