evidence: President Donald Trump made a surprise visit to American troops in Iraq on Wednesday, his first journey to an active combat zone since he took office. The president, who was joined by first lady Melania Trump, spent three hours on the ground with U.S. forces and met with the U.S. ambassador and commanders on the ground. [...] In October, Trump told The Associated Press that he did not think it was "overly necessary" to visit a military base in a combat zone, such as Iraq and Afghanistan.
