The conservative Committee for Justice released a web ad today accusing Sonia Sotomayor of having "led a group supporting violent Puerto Rican terrorists."

The ad begins with a comparison to former Weather Underground member William Ayers. The group says it plans to air the ad on TV.

Though it's not explained further in the ad, the group's claim centers on a comment by an official with the Puerto Rican Legal Defense and Education Fund (PRLDEF), with which Sotomayor worked in 1990 when New York Mayor David Dinkins referred to the Puerto Rican nationalists who attacked the U.S. Congress in 1954 as "terrorists." The PRLDEF official said those remarks were insensitive.
