WASHINGTON (Reuters) - President Barack Obama will name Warren Buffet as one of fifteen winners of the 2010 Medal of Freedom, a White House official said on Wednesday.

Buffet, one of the world's most successful investors who has donated a vast chunk of his multibillion dollar fortune to charity, will receive the medal at a White House ceremony early next year. The award is the highest U.S. civilian honor.

Buffet is one of Obama's closest defenders in the business community and the president has sought his counsel dating back to the 2008 presidential campaign and since.
