preliminarily, based on the information we have this far, we show him in michigan as early as june 18. i can't say definitely he wasn't here sooner, but we show activity in michigan on june 18. as a result of the attack yesterday, we've now conducted over 20 interviews of witnesses and we expect to do additional interviews as we continue to go through the information that we have obtained through a variety of investigative means. we've also executed several search warrants, and those search warrants could lead to other search warrants, and i won't get into the details. i'll get into one specific search we conducted -- >> we just wanted to dip in and listen to the fbi there in the wake of that stabbing that is now being investigated as a terrorist act led by the fbi here. it was this 49-year-old man who apparently intentionally targeted this airport police officer at the flint, michigan, airport, and so he's now been -- he's been in court. he's charged with violence at an international airport. we're going to watch that and
