The Knox County Commission is scheduled to discuss a controversial immigration enforcement deal following a report published last week by Knox News and Compass Knox that revealed the Sheriff's Office didn't secure commission approval for the initiative as required by state law. Commissioner Charles Busler asked to put the issue on the body’s April agenda, which means it will be up for discussion at either the April 19 agenda review or the full April 26 meeting, or possibly both. The commission agenda was first published online Tuesday. Commission manager Drucilla Stills told Knox News that Busler requested the item be added Thursday, the day the report published.
