Comcast could drop its $45 billion bid for Time Warner Cable as early as Friday, a source told CNBC on Thursday. Time Warner Cable declined to comment to CNBC on an earlier report of an intent to drop the bid. A spokeswoman for the U.S. Federal Communications Commission also declined to comment. A spokesman for the Department of Justice told CNBC the agency would continue its review of the proposed deal and it was "not aware of anything" related to a dropped merger bid. Earlier on Thursday, The Wall Street Journal reported the deal had hit a possible snag after the FCC's staff recommended that agency set up a hearing over Comcast's proposed acquisition. Comcast owns NBC Universal, which is the parent company of CNBC, NBC News and this site.
