TOPEKA — A Senate committee withheld approval of a Lawrence attorney’s nomination to serve on the state’s public defender board after a senator said she was an “activist.” Sen. Tim Shallenburger, a Baxter Springs Republican serving on the Confirmation Oversight Committee, said Tuesday he wouldn’t vote to affirm attorney Meredith Schnug’s nomination to the Kansas State Board of Indigents’ Defense. Instead, he asked that her nomination be left to the full Senate when lawmakers return in January.
