Senate Minority Leader Mitch McConnell (R-KY) is considering his next move after he plans to step down as the longest-serving Senate leader in November, according to sources familiar with his thinking.

If Republicans win the Senate majority in November, there will be a new batch of faces at the helm of every committee and seniority is heavily considered when the assignments are made. Senate Republicans determine their committee assignments by having each senator submit requests and rank their preferences. Seniority as well as those rankings are factored into the final decisions.
