Hawking added that even though everyday life in the USA seems to be continuing much the same as it always has, he fears that the new administration will have a chilling effect on the scientific community.
"I have many friends and colleagues [in the US] and it is still a place I like and admire in many ways... but I fear that I may not be welcome", Hawking said on ITV's "Good Morning Britain" on Monday morning.
