President Barack Obama is bypassing GOP opposition to make three more appointments while Congress is out of town -- these to the National Labor Relations Board.

The move came hours after Obama used a similar tactic to install former Ohio Atty. Gen. Richard Cordray to head the new Consumer Financial Protection Bureau.

Both moves infuriated GOP leaders, who threatened legal action and warned that Obama was setting a dangerous precedent by ignoring the will of Congress.

The NLRB has been a target of Republicans who claim it has tilted too far in favor of unions. Senate Republicans had pledged to block Obama from making any further board appointments

The agency usually has five members but has been operating with just three. It lost another member this week, leaving it unable to reach major decisions.
