Omar Mateen had run in's with FBI at least twice, once in 2013 when he made threatening comments to co-workers ?including possible ties to terrorist activities,? an FBI spokesman said Sunday. Mateen was investigated again in 2014, over possible connections to a ?American suicide bomber,? the FBI said.


Officials say Omar Mateen, the man suspected of the deadliest shooting spree in U.S. history, purchased the guns used in the attack legally within the past week.
