At a rally on Wednesday night, supporters of Donald Trump broke out in a chorus of "send her back!" chants, targeted toward Ilhan Omar, a Somali-born congresswoman from Minnesota.

The chant came just days after the U.S. president took to Twitter, to attack four congresswomen of colour, suggesting they "go back and help fix the broken and crime-infested places from which they came."

All of this has set off a debate in the media, on how to cover Trump and racism.

On today's Front Burner, we talk to Adam Serwer, staff writer with The Atlantic, about journalistic objectivity, Trump, the media and the term "racist."
