Christie's biggest backer to support Romney

Billionaire venture capitalist and Home Depot co-founder Ken Langone, who aggressively pushed Chris Christie to enter the presidential race, has decided to throw his support behind Mitt Romney, CBS News has confirmed.

Langone's decision, which comes hours after Christie announced he would forgo a run, signals that the big donors who have spent much of the year seeking a Romney alternative may finally have decided to get behind the former Massachusetts governor.
