"I'm an actor. It's like, why should you be talking about politics? That's an easy place to go," Costner said in an interview Monday with WBZ-TV.

"But I pay taxes. I have children. It matters to me the life, the world that they're gonna inherit," the "Field of Dreams" star said. "And I don't like the direction we're going."


Costner appeared at a campaign rally for Buttigieg on Monday in the Granite State on the eve of the nation’s first presidential primary. It's not the only campaigning the 65-year-old performer has done for the former mayor — he also took to the stage at a Buttigieg event in Iowa last month.

"Politics is a thing that a lot of us don't get involved in," Costner said Tuesday in an interview with MSNBC's Stephanie Ruhle, "and what we realize once in a while is by not getting involved, politics can run right over you."

"I like to believe his voice will carry through," Costner, who supported then-Sen.

Buttigieg brought additional star power to New Hampshire, too. Actor Michael J. Fox was with the White House hopeful during an event over the weekend. "We have a very stable Rhodes scholar," the "Back to the Future" actor quipped of Buttigieg at Keene State College.

Other entertainers have also headed to the state to offer some high-profile support for their candidates of choice.
