Microsoft seen as potential Twitter bidder

Twitter, which is said to be entertaining buyout bids, may also have Microsoft as a potential suitor, CNBC reports, citing an informed source.

CNBC's David Faber reported on "Closing Bell" that the social media giant is moving closer to a formal sale process for the company, according to sources familiar with the situation. However, he said, that does not mean it is in that formal process yet.
