Senate Minority Leader Mitch McConnell (R-KY) is insisting to his conference that imposing term limits on Senate leadership is a bad idea, according to sources familiar with a recent closed-door GOP lunch.

The Kentucky Republican, who has served 18 years as Senate GOP leader, is attempting to preserve how leadership operates as he is set to step down from the position and as his possible successors consider making major changes to the direction of the conference.
