Just in case there was any doubt, former New York mayor Michael Bloomberg (I) made clear Wednesday that he won't entertain the idea of running for president in 2016.

Bloomberg has long been rumored as a potential third-party or independent candidate for president, but he sought to put the 2016 talk to bed early during an appearance on the "Today" show.

"No is the answer -- plain and simple," Bloomberg said. "I'm going to spend the rest of my life trying to make a better world for myself, for my kids, for my grandchildren..."

Bloomberg was appearing on the show to promote his new gun-control effort.
