I followed him on Twitter for the past 3 years. (It's part of my job to keep up with media people.)
He would frequently live-tweet British soccer games, or talk about British soccer in general. I think British soccer made up 60% of his tweets.
About 10% of his tweets would be retweeting people who misspelled "you're."
And another 15% would be about guns, which got annoying (hey, I'm on his side).
I just looked at his Twitter, with 4 million followers, and, yes, it still is packed with British soccer tweets.
The point is he never tried to assimilate. He was adamantly British through and through, which could be a problem on CNN at 9 pm.
