Arizona GOP sues to limit mail-in ballots in US Senate race

PHOENIX (AP) - Republicans filed a lawsuit Wednesday night to challenge the way some Arizona counties count mail-in ballots as election officials began to slowly tally more than 600,000 outstanding votes in the narrow U.S. Senate race -- a task that could take days. Republican Rep. Martha McSally and Democratic Rep. Kyrsten Sinema were separated by a small fraction of the 1.7 million tabulated votes.
