Yes, although I think he was only arrested, not charged and convicted. He was let off easily, but did not have a felony conviction, so far as I have seen.....
As for his trip to Russia, it was Jan. to July 2012, I believe.
That was in 2011. the unknown state was Russia. So, if Russia suspected he was trying to join an underground group, and believed he would be leaving the US to pursue that interest, why did Russia allow him into the country in 2012? Were the Russians as unaware as the FBI of his presence in their country because his name was misspelled? Did he even make it to Russia, and did he go anywhere else while he was overseas? The FBI/CIA need to actively pursue this.
