PHOENIX (AP) — Candidates in Arizona's close U.S. Senate race put the finishing touches on their campaigns Monday.
GOP congressman Jeff Flake crisscrossed the state in a bid to tie up a contest that initially favored him.
Former surgeon general Richard Carmona ramped up get-out-the-vote efforts in his attempt to become the state's first Hispanic U.S. senator.
Democrats, meanwhile, complained that automated calls made this past weekend by the Flake campaign gave some Democratic voters erroneous information on the location of their polling places.
The Flake campaign attributed the incorrect locations to outdated information in a database.
The Arizona Democratic Party has accused Flake's campaign of interfering with voting and says it has complained to federal authorities about the erroneous information.
FBI spokesman Manuel Johnson declined to comment on the complaint.
