Northfield Mayor Joseph Lee Lansing will attend his omnibus hearing on Dec. 17 at 1:30 p.m. in Rice County District Court in Faribault. District Court Judge Warren E. Litynski set the date Wednesday afternoon after an arraignment that lasted about 10 minutes. The mayor is facing five charges of misconduct by a public official and two charges of conflict of interest by a public official. Lansing, casually dressed in jeans and a sweater, appeared in good spirits during his arraignment hearing, and chatted with people before and afterward. His attorney is Tom Dunnwald.
