Irish mixed martial arts fighter Conor McGregor, who has been found liable of sexual assault, met Donald Trump during a Saint Patrick's Day visit on Monday during which he lashed out at illegal immigration in Ireland. "Ireland is at the cusp of potentially losing its Irishness," said McGregor during an appearance in the White House briefing room alongside the president's press secretary, Karoline Leavitt. "The illegal immigration racket is running ravage on the country," added the fighter, wearing a green business suit to mark Saint Patrick's Day, the centuries-old celebration of his homeland.
