The AFL-CIO, accusing President Reagan of an attempt at “ideological court-packing,” urged the Senate to reject Reagan’s nomination of Judge Robert H. Bork to the Supreme Court. In a four-page statement, the executive council of the labor federation said Bork’s record and career “make it plain that he is a man moved . . . by an overriding commitment to the interests of the wealthy and powerful in our society.” The AFL-CIO’s position was expected. Federation officials were scheduled to decide today how much money to spend in its campaign to defeat Bork’s confirmation.
