[JURIST] The Republican lawmaker expected to head the Senate Judiciary Committee early next year has issued a stern warning to President Bush against appointing Supreme Court justices who would seek to overturn abortion rights, or who are otherwise too conservative to sit on the high court. Sen. Arlen Specter (R-PA), a moderate Republican who will likely take over the Judiciary Committee's top spot from Sen. Orrin Hatch (R-UT), spoke Thursday of Senate Democrats' recent success in blocking the president's conservative judicial appointments, saying that he expects Bush "to be mindful of those considerations". Sen. Specter also lamented what he calls a lack of judicial heavyweights on the current Supreme Court. AP has more.
