Obama, along with Senate Majority Leader Harry Reid (D, Nevada) endorsed Schatz on May 31.
The 30-second TV spot features quotes from Obama touting Schatz as "protecting Hawaii's future" and "fighting every day on behalf of middle class families."
It ends with a quote:
"It's important to return Brian Schatz to the Senate."
Schatz and Hanabusa are facing off in the Democratic primary election in August.
