Early reports indicated he was a citizen. No?
According to police statement to the media, Cetin is a Turk who was brought to the U.S. as a child when his mother married a Navy enlisted man while he was deployed in the region. Arcan Cetin is a permanent legal resident of the U.S., but there is no evidence that he has ever been naturalized as a citizen.
Washinngton State residents do not register by party, but we know that Cetin posted on social media: “We Win I vote for Hillary Clinton”. That is indisputable and one can reach the very logical conclusion that he voted for Clinton in the Pimary election and plans to vote for her again in the General in November.
