It's official: Sen. Al Franken on duty for Minn.

Minnesota officially has two senators once again and Al Franken can now be referred to as Sen. Al Franken. Did this more than eight-month battle just end with an oath and signature? It sure did.

The actual swearing-in was shorter than the sustained applause that followed as Franken made his way around the Senate chamber for handshakes and hugs from his new colleagues. Franken was escorted by Sen. Amy Klobuchar and former Vice President Walter Mondale.

Franken will start work on the Senate Judiciary Committee, Indian Affairs and the Special Committee on Aging. He will also serve on the Health, Education, Labor and Pensions committee once the mark-up is completed on the health care bill.
