The U.S. Department of Agriculture is marking its 150th anniversary Tuesday morning at 10:30 EST with a live webcast of a celebration marking the date at the department’s South Building in Washington.

President Abraham Lincoln signed legislation establishing the department on May 15, 1862, in the midst of the Civil War. The creation of the department was part of an enormous expansion of the federal government during the war.

Secretary of Agriculture Tom Vilsack will be joined by Joe Scarborough and Mika Brzenzinski, co-hosts of MSNBC’s “Morning Joe.” Also participating will be Chuck Leavell, keyboardist for the Allman Brothers and the Rolling Stones, who is a Georgia tree farmer and co-founder of environmental information Web site Mother Nature Network.

Former Washington Redskins Art Monk and LaVar Arrington, who are involved in “Fuel Up to Play 60,” an in-school nutrition and physical activity program supported by USDA, will also give presentations.

The event is scheduled to last about 80 minutes.
