CNN anchor Anderson Cooper accused President Trump’s daughter-in-law Lara Trump of being insincere in the explanation she gave about the “send her back” chants that broke out during a Trump campaign rally in North Carolina.

In an interview Friday with Fox Business, Lara Trump said the crowd began chanting “send in back” in reference to Somali-born Rep. Ilhan Omar, who is an American citizen, without being prompted. She also claimed “it wasn’t the whole crowd, it was just a couple of people right there in the front, but [the president] didn’t say it.”
