Arizona: Barber team open to legal challenge as recount looms | CNN
An attorney for Rep. Ron Barber (D-Ariz.) is raising the prospect of a long, drawn-out battle over control of his Tucson-area district, a seat once held by his former boss Gabby Giffords, as his contest with Republican Martha McSally looks increasingly likely to head to a recount. Kevin Hamilton, Barber's legal counsel, said Wednesday that the campaign isn't taking "anything off the table" in potentially challenging the outcome of the race when it's certified next month. "There are lots of potential options. There is the ability to file an election contest under state law. There's a recount that goes forward, and as we've seen in other states that can affect the outcome of the election," he said. "There's a range of options and we're not taking anything off the table."
