Biden, who has made a string of high-profile gaffes this week, continued the trend during a visit to the Iowa State Fair, where he was asked by a student “how many genders” exist. “There are at least three,” the 76-year-old Biden responded, according to video of the encounter captured by Turning Point USA. When pushed to name all three genders by the student, Biden retorted by saying, “Don’t play games with me, kid.”
