[JURIST] NARAL Pro-Choice America [advocacy website; press release] said late Thursday that it is pulling a widely criticized television spot [JURIST report] that linked US Supreme Court nominee John Roberts to anti-abortion bombers, claiming its efforts to expose Roberts' record have been "misconstrued." Senator Arlen Specter [official website] (R-PA), a pro-choice Republican and chairman of the Senate Judiciary Committee that will question Roberts in September, had called the ad "blatantly untrue and unfair." NARAL President Nancy Keenan [profile] said the group would run a new ad showcasing Roberts' advocacy for overturning Roe v. Wade and his "arguments against using a federal civil rights law to protect women and their doctors and nurses from those who use blockades and intimidation." AP has more.
