CHICAGO (AP) — Democratic Congresswoman Tammy Duckworth says she'll support the Iran nuclear deal despite "serious concerns" about threats to Israel.

The 2016 U.S. Senate candidate said in a statement Wednesday the agreement is imperfect. But she says it gives the U.S. and its allies "the most realistic and effective course of action currently available to stop Iran's nuclear weapons program."

Duckworth is looking to unseat Illinois Republican Sen. Mark Kirk, one of the agreement's most vocal opponents.

Kirk campaign manager Kevin Artl says Duckworth "put politics and her party" before stopping the spread of terrorism.

Democratic candidate Andrea Zopp, the former Chicago Urban League CEO, supports the agreement. She said Duckworth's delay in taking a position showed a lack of leadership.

Duckworth says she spent "many hours" studying the deal before deciding.
