Actor Peter Fonda targets President Donald Trump’s 12-year-old son Barron in a late-night Twitter rant about the separation of immigrant families at the U.S. border. In an all caps tweet that he later deleted, SF GATE reports Fonda saying, “We should rip Barron Trump from his mother’s arms and put him in a cage with pedophiles, and see if mother will stand up against the giant a–hole she is married to.”
