A group critical of the president's foreign policy has unleased an ad in key swing states accusing President Obama of favoring Iran over Israel, highlighting how U.S. officials didn't storm out of the United Nations this week when Iranian President Ahmadinejad said the Jewish state would be eliminated.

The group Let Freedom Ring sent the ads to Pennsylvania, Ohio, Virginia and Wisconsin as part of a $7 million campaign to question Obama's support for Israel.

The ad uses visuals to make their case, noting that the U.S. delegation did not storm out of the chamber as did Israel's U.N. Ambassador Ron Prosor, then asks: "Why did your administration sit with Iran rather than stand with Israel? Why Mr. President, Why?"

Let Freedom Ring president Colin Hanna said, "His abandonment of Israel, America's closest ally, is just the latest example that we are exposing."
