evidence: Pat Nixon also visited a combat zone in South Vietnam in July 1969. Several first ladies have traveled to war zones — including Eleanor Roosevelt, who visited England in 1942 and the Pacific theater in 1943 during World War II. Most recently, Melania Trump accompanied then-President Donald Trump on a surprise visit to Iraq in December 2018. Former first lady Michelle Obama and late night talk show host Conan O’Brien went to the Al Udeid Air Base in Qatar in November 2015 to talk with and entertain the troops. And former first lady Laura Bush visited troops in Afghanistan twice, in March 2005 and again in June 2008. [...] Correction, July 9: We incorrectly wrote that Pat Nixon was the first first lady to visit a combat zone, citing the National First Ladies’ Library as our source. A reader rightly pointed out that Eleanor Roosevelt visited combat zones during World War II. We have corrected the story. We thank the reader for bringing the error to our attention.
