Sen. Luther Strange’s campaign rolled out a late ad blitz highlighting President Donald Trump’s endorsement on Thursday morning, less than a week before the special Senate primaries in Alabama.

Trump tweeted an endorsement of Strange earlier this week. Strange was appointed to fill Attorney General Jeff Sessions’ old Senate seat and is running in the crowded special election to complete Sessions’ term.

"President Trump says Luther Strange is the best conservative to pass our agenda," says the narrator in Strange’s new 30-second television spot, while Trump’s tweet appears onscreen. "Tweeting, ‘Luther Strange has done a great job representing the great people of the great state of Alabama. He has my complete and total endorsement!’"

"Others attack our president. I’m fighting with him to drain the swamp and repeal Obamacare," Strange says to the camera, referencing GOP Rep. Mo Brooks’ criticism of the president’s recent spat with Sessions and the Strange endorsement.

The radio ad focuses on Brooks, one of Strange’s top rivals in the primary.

"Brooks keeps attacking our president," the radio narrator says, before playing quotes of Brooks saying, "I don’t think you can trust Donald Trump with anything he says." Brooks supported Ted Cruz during the 2016 presidential primaries and repeatedly attacked Trump during that time.

"Mo Brooks, a Never-Trump career politician," the narrator continues, before pivoting to praise of Strange.

Senate Leadership Fund, the super PAC controlled by allies of Senate Majority Leader Mitch McConnell, is also backing Strange and has released a short 6-second digital spot touting Trump’s endorsement.
