Sen. Amy Klobuchar touts the presidential campaign of Hillary Clinton in a new radio ad airing across Minnesota. 

In the 60-second ad released Wednesday, Klobuchar tells of how then-Secretary of State Clinton helped a group of Minnesota women who were encountering obstacles getting children they adopted from Haiti into the state after the devastating 2010 earthquake in that country.

"I called Hillary Clinton," Klobuchar says in the ad. "Soon, those babies came home to Minnesota and their families. That's the Hillary I know -- she gets things done." 

The ad can be heard here.

Clinton is locked in a close contest with Vermont Sen. Bernie Sanders in Minnesota, which holds it caucus next Tuesday. Both Clinton and Sanders have aired television advertisements in Minnesota.
