Longtime national sports broadcaster Brent Musburger took to Twitter on Saturday to make a “joke” that predictably divided his audience.

Musburger posted a photo from President Donald Trump’s rally in Montana in which several men appear in American Indian headresses. Under the photo, Musburger wrote: “Elizabeth Warren’s ‘relatives’ backing Trump in Montana!”

Sen. Warren (D-Mass.) claims to be of Native American descent, something that Trump and others have mocked repeatedly. Trump frequently refers to Warren as “Pocohontas.”

The tweet by Musburger brought praise and scorn for the 79-year-old radio voice of the Oakland Raiders. The team had no comment.

Here are a couple examples of the responses Musburger received:

Hey Brett love VSIN but this crap will keep me from listening. Stick to point spreads. — Patrick Conner (@pdconner52) November 4, 2018

In 1968, Musburger wrote on Tommie Smith and John Carlos's protest of racial injustice in the US on the medal stand during the 1968 Olympics. He said, “Smith and Carlos looked like a couple of black-skinned storm troopers" who were "ignoble," "juvenile," and "unimaginative." — Stephanie McCarroll (@SoCaliSteph) November 4, 2018
