evidence: Editor's note: On Wednesday, NBC News compiled a list of every Christmastime visit to active troops by a president since 2001. That list, as detailed in the article below, showed that former Presidents George W. Bush and Barack Obama visited troops on or before Christmas every year since 2003, and President Donald Trump did so in 2017. As of the end of Christmas Day 2018, Trump had not visited troops during the holiday season, and had announced no plans to do so. The article was correct, but on Dec. 26, the situation changed. Trump and the first lady, Melania Trump, made an unannounced visit to troops in Iraq. As a result, the thrust of this article is no longer correct, even if it was at the time. In the interest of transparency, we are keeping the article on NBCNews.com so that the record will reflect the situation on the day the article was published, and are directing readers to the article about Trump’s Iraq visit here. [...] In recent months, Trump has taken heat from critics for not visiting troops in an active combat zone, after canceling a trip to an American military burial ground outside of Paris last month due to weather and skipping the traditional Veterans Day visit to Arlington National Cemetery just two days later. [...] Trump made the trip to Arlington several weeks later to lay a wreath as part of Wreaths Across America, but still has yet to visit an active combat zone.
