Senate President Pro Tempore-designate Greg Treat on Thursday announced the full committee assignments of Senate Republicans for the 57th Legislature.
 Treat also announced meeting times and locations of Senate committees for the 2019 session. The standing committees remain the same from the past session; however, the membership of the Appropriations Committee is changing. In the past, all members of the Senate served on the Appropriations Committee. Pro Tem-designate Treat is appointing the chairs and vice chairs of the Finance Committee and the chairs and vice chairs of the Appropriations Subcommittees to serve on the full Appropriations Committee.
 Per Senate rules, Democratic leaders will make their committee assignments, including five appointments to the Appropriations Committee.
