ST. PAUL, Minn. — U.S. Sen. Amy Klobuchar says she’ll vote for the Iran nuclear deal.

The Minnesota Democrat threw her support behind the plan in a Monday statement. She said it’s imperfect but it offers the “best available option to put the brakes on Iran’s development of a nuclear weapon.”

Klobuchar’s support comes after a top Senate Democrat, Sen. Chuck Schumer, announced last week he’ll oppose the deal.

President Barack Obama needs at least 34 senators to back his plan in order to keep it in place.

Klobuchar makes for 17 Democrats in favor. Fellow Minnesota Democratic Sen. Al Franken’s spokesman Michael Dale-Stein says he’s strongly leaning toward supporting the deal.
