As Mitt Romney addressed the press in Downing Street, he was asked about his earlier comments about "disconcerting" stories about the UK's readiness for the Olympic Games.
"I don't know of any Olympics that's ever been able to run without any mistakes whatsoever but they're small.
"I was encouraged to see something that could have represented a real challenge which was immigration and customs, officers on duty; that is something which was resolved and people are all pulling together."
