The guy strongly resembles Gordon but, that isn't Gordon. The guy in the picture is too young and has a thinner, smoother face than Gordon.Looks like him.
Looks a good bit like him, but 99% sure it's not, the nose and hair are slightly wrong (this is my worthless superpower ... it's not 100% reliable). Plus that's not his wife or daughters (and I don't think he's stepping out to a hugely public event with "someone else")
