WASHINGTON (AP) — Rep. Paul Ryan’s plan to take over one of the most powerful committees in Congress could hit a snag when lawmakers return after the midterm elections.

Ryan, the Republican Party’s candidate for vice president two years ago, has been telling colleagues for much of the past year that he wants to chair the powerful House Ways and Means Committee in the new Congress next year. The post could provide a platform for the Wisconsin Republican to launch a possible bid for president in 2016.
