Trump backtracks on suggestion U.S. troops could fire on migrants

What I don't want is I don't want these people throwing rocks," Trump told reporters outside the White House."If they do that with us, they're going to be arrested for a long time."Trump's rhetoric on shooting migrants drew criticism from human rights groups that said he was stoking fear ahead of next week's congressional elections.Calling migrants a national security threat "is as absurd as it is cruel," advocacy group Human Rights First said in a statement.
