Unlike the celebrations surrounding his first swearing-in, President Obama’s inauguration committee has accepted money from unions as well as several corporations to help foot the bill for this year’s festivities, according to the latest list of inaugural contributors.

The 2013 Presidential Inaugural Committee updated a list of “benefactors” on its website Friday night to include eight unions and several major corporations.

In 2009, inaugural planners banned corporate and union donations and still managed to raise $53 million — all from individual donors.

The money pays for some of the expensive extras for the swearing-in-ceremony such as Jumbotrons on the National Mall, as well as the children’s concert, private brunches, two inaugural balls and the star-studded slate of performers including Alicia Keys, Katy Perry, Stevie Wonder and Marc Antony.

With many donors tapped out from the most expensive presidential campaign in history, this year organizers hope to amass $40 million to $50 million to pay for the festivities and have turned to businesses and unions — the very monied special interests Mr. Obama once eschewed on the campaign trail as too powerful — for help.

The list of unions include the American Federation of Government Employees, the American Postal Workers Union, the International Association of Firefighters, and the International Brotherhood of Electrical Workers.
