Massachusetts U.S. Senator Edward Markey is planning to hold a ceremonial swearing-in ceremony at Boston's historic Faneuil Hall.
Markey was actually sworn in last month by Vice President Joe Biden during a brief ceremony in the Senate chamber in Washington.
Today’s event is a chance for more of the Democrat's supporters and members of the public to mark the start of his tenure in the Senate.
Markey defeated Republican Gabriel Gomez in a June special election to fill the seat left vacant by John Kerry's resignation from the Senate to become secretary of state.
