President Trump and his wife, Melania Trump, have greeted US troops in Germany. The president, making his second visit to US troops abroad in the space of a day, stopped at Ramstein Air Force Base on his way back from Iraq, the AP reports. Trump slowly made his way down a rope line at the Ramstein base, shaking hands, chatting, and posing for photos. Some service members held up "Make America Great Again" caps for Trump to sign. The president's earlier visit to a base in western Iraq was his first to US forces in harm's way overseas. Both visits were unannounced. (More President Trump stories.)
