At 8:13am this morning the wife of Orlando mass shooting gunman Omar Mateen, Noor Salman, was arrested by the FBI in San Francisco California.  Salman is expected to appear in federal court in Oakland on Tuesday at 9:30 a.m  The case is being handled by the U.S. Central District Court in Florida. Neither charging documents nor federal affidavits were online on Monday.

In June 2016, a source close to the family told NBC News that Mateen sent his wife a text message during the rampage, asking her, “Do you see what’s happening?” After swapping texts, she tried to call him.
