Yesterday, someone at a @KamalaHarris event called Pres. Trump “mentally retarded.”

The 2020 candidate told @CHueyBurns the term is “incredibly offensive” and said in 2019 you would think "people would have a much better understanding of how hurtful a term like that can be." pic.twitter.com/01amMnkaqi
