Addressing supporters in Greenville, North Carolina, Trump spent a good portion of Wednesday's event attacking "The Squad"—the four-strong group of progressive Democratic female representatives of color—about whom he tweeted racist tropes at the weekend.His angry online tirade declared that the women—three of whom were born in the U.S. and all of whom are American citizens—should "go back" to their countries of origin. He also accused them of "spewing some of the most vile, hateful and disgusting things ever said by a politician."Wednesday's rally was imbued with the aggrieved, uncompromising and tribal sentiment that has become synonymous with the president's campaign events. The crowd even began chanting "Send her back! Send her back!" at one point during Trump's attacks on Omar, as the president repeated false and debunked accusations previously used to smear the Minnesota congresswoman.
