Almost three months to the day since AT&T first announced its $39 billion bid for T-Mobile, federal scrutiny of the deal is well under way. AT&T has filed its paperwork with the Federal Communications Commission, the public is weighing in on the FCC's Web site, and opponents and supporters are lining up.

Though the U.S. Senate has held hearings as well, only the Department of Justice and the FCC have the official power to approve or deny the merger. AT&T does not have to seek formal approval at the state level, but state governments can make the transaction more complicated if they bring antitrust lawsuits. And as CNET's Maggie Reardon has reported, states have extensive oversight over communications through the regulation of rates, cell tower placement, and consumer complaints.

That's why it doesn't hurt for AT&T to lobby for the merger not only in Washington, D.C., but also in state capitals across the country (the carrier has even gotten into a tussle with Sprint over a possible state review in West Virgina). And at the time of this writing, AT&T has been successful. Though three states are taking a closer look, 17 27 state governors have voiced their approval.

Below the governor level, the attorneys general of Arkansas, Utah, Alabama, Georgia, Kentucky, Michigan, Mississippi, North Dakota, South Dakota, West Virginia, and Wyoming sent a joint letter of support to the FCC on July 27. And on September 16, the attorneys general of California, Illinois, Massachusetts, New York, Ohio, Pennsylvania, and Washington sent a letter opposing the merger. Months earlier, New York Attorney General Eric Schneiderman announced that his office would "undertake a thorough review of AT&T's acquisition of T-Mobile" and analyze the merger for "potential anticompetitive effects on consumers and businesses."

We'll add to this list as events unfold, but here's how the states are lining up so far.
