AUGUSTA — Adjutant Gen. John Libby has addressed a joint session of the Maine Legislature, marking the first time someone in his post has done do.

Today’s address to lawmakers is also the last for Libby, who’s submitted his resignation effective March 16. Libby heads the Maine National Guard and is commissioner of the state Department of Defense, Veterans and Emergency Management.

In his address, Libby said Congress has been “generous” in its support of the Maine National Guard, that governors he’s served under have been attentive to the needs of the Guard and its members and that legislative support has been “exceptional.”

But he said the future role of the National Guard and reserves is in question. He said there “may be a limit on what we can do.”
