HARRISBURG, Pa. (AP) – A Democrat in Pennsylvania’s state Senate is switching his registration to become an independent and will caucus with the Republican majority.

Sen. John Yudichak of Luzerne County said Tuesday that registering as an independent is the only way he can faithfully and fully serve the people of his northeastern Pennsylvania district. Yudichak’s departure comes after Democrats picked up six seats in the past year.
