"As we watched the events and the response from President Trump over the weekend, we too felt that he missed a critical opportunity to help bring our country together by unequivocally rejecting the appalling actions of white supremacists," McMillon wrote in a statement posted to Walmart's website Tuesday.
Trump drew widespread criticism Saturday after he condemned the violence in Charlottesville "from many sides," without specifically denouncing white supremacists or racism.
On Monday, he released a second statement saying the White House condemns "in the strongest possible terms this egregious display of hatred, bigotry, and violence on Monday."
McMillon said Trump's remarks on Monday "were a step in the right direction and we need that clarity and consistency in the future."
