In his remarks to a crowd on the Fourth of July at the White House, President Trump said he never heard of the term "second lady," referring to the vice president's wife, Karen Pence.
"There is one military family here I am especially excited to recognize. Our great Vice President Mike Pence and our second lady -- never heard that term before but that's what they say, and she is some lady, that I can tell you--of the United States Karen Pence, are here along with their son Maine First Lieutenant Michael Pence."
Trump's confusion likely drew eyebrows. On the White House's website, Karen Pence is overtly described as "Second Lady of the United States."
Though unconfirmed, Trump's confusion could have sprouted from the eight years of the Obama administration, when former Vice President Joe Biden's wife, Jill Biden, was often referred to as "Dr. Jill Biden," instead of the "second lady." That's because, according to the LA Times, Mrs. Biden was thought to be the first second lady to hold a paying job when her husband was in office.
