WASHINGTON (AP) — Key parts of Arizona's immigration law have been struck down by the Supreme Court -- but not the provision requiring police to check the immigration status of someone they suspect is in the United States illegally.

Even there, though, the justices said the provision could face additional legal challenges. And while upholding the "show me your papers" requirement for now, the justices took the teeth out of it -- by prohibiting police officers from arresting people on minor immigration charges.

OKLAHOMA CITY (AP) — An Oklahoma City dentist accused of submitting claims for dental services she didn't provide has been charged in federal court with health care fraud.

The Oklahoma Attorney General's office says 44-year-old Robin Lockwood faces one count of health care fraud.

OKLAHOMA CITY (AP) — A Republican candidate for a state House seat in northwest Oklahoma is trying to downplay a photograph in which he is seen wearing a swastika-adorned Iron Cross medallion around his neck.
