At a recent rally in North Carolina, Pres. Trump slammed some foreign born Democratic lawmakers.
Primarily, he hit out against Minnesota Congresswoman Ilhan Omar, a naturalized US Citizen.
At the rally, some attendees chanted "send her back" in reference to Omar.
According to a Business Insider pill more than a third of Republican primary voters say they supported the chant.
The poll mirrored a partisan divide when it comes to perceived racial attitudes.
