Senate Majority Leader Nate Libby, D-Lewiston Four-term state Sen. Nate Libby said Monday he’s going to scale back his legislative work by giving up his position as majority leader. Libby, a Democrat from Lewiston, said he’ll remain as a senator but since taking a job in December as president of Community Concepts Finance Corp., he no longer has time for the many commitments that a leadership post carries. Libby said he’ll give up the post on Feb. 1, when Democrats in the Senate will elect a new majority leader to serve as second-in-command to Senate President Troy Jackson, D-Allagash.
