evidence: President Trump and first lady Melania Trump have made a surprise trip to Iraq to visit U.S. troops. The trip marked Mr. Trump's first visit to Iraq, as well as his first visit to a combat zone as commander-in-chief. "@FLOTUS Melania and I were honored to visit our incredible troops at Al Asad Air Base in Iraq. GOD BLESS THE U.S.A.!," Mr. Trump wrote on Twitter Wednesday afternoon. He posted a short video clip that shows him greeting the troops, shaking hands and signing autographs. The president and first lady met with service members at the Al Asad Airbase on the outskirts of Baghdad. They were on the ground in Iraq for about three and a half hours. Mr. Trump had been criticized for not visiting troops during the holidays — a long-held tradition for American presidents.
