“Obama is 6 1, and then add shoes.”
Shoes? Is Comey barefoot? If they both are wearing shoes then shoes have little to do with anything unless one is wearing high heeled cowboy boots and the other is wearing dress shoes.
Very tall people have a tendency to not where shoes that raise their height and visa versa for short people.
For the record, I saw another photo of the 3 together walking at the White House.
Here you go.
