TRAVERSE CITY, Mich. (AP) — Michigan Sen. Carl Levin and some fellow Great Lakes lawmakers are asking their congressional colleagues to fund programs designed to preserve and protect the lakes.

The push from the Great Lakes senators comes as President Barack Obama’s budget for next year requests the least spending yet on the Great Lakes Restoration Initiative, a cleanup program for the lakes that his administration has championed.
