The Kentucky General Assembly is poised to vote Friday on a $19 billion, two-year state budget that provides $3.5 million to help the Kentucky Horse Park and $2.5 million to start the redevelopment of Rupp Arena. Leading lawmakers agreed on a compromise budget just minutes before a self-imposed deadline of 3 a.m. Thursday, giving legislative staffers enough time to make requested changes in the bill before rank-and-file members vote on it Friday.
