Amazon halts sales of shirts that used a derogatory term to refer to Kamala Harris.

Amazon this week removed shirts from its online marketplace that used a derogatory word to refer to Senator Kamala Harris of California, the Democratic nominee for vice president, the company said on Wednesday.

The shirts featured a fictitious campaign logo for Ms. Harris and Joseph R. Biden Jr., the Democratic presidential nominee, that referred to Ms. Harris using a slur associated with promiscuity.

“All sellers must follow our selling guidelines and those who do not will be subject to action including potential removal of their account,” an Amazon spokeswoman said in an email. “These products have been removed.”

USA Today, which first reported on the step taken by Amazon, said that one seller, The Oxygen Bandit, sold T-shirts, tank tops, hoodies and sweatshirts with the phrase on its Amazon store.
