Rev. Al Sharpton bashed Donald Trump's Tuesday night message about black issues, calling it a ploy to improve how white voters perceive the Republican nominee.

"I think that he's trying to modify his image to whites and particularly independents because if he was really trying to go after black voters, he would have went into Milwaukee or went anywhere. He has not gone to any black audience," Sharpton told Politico Wednesday about Trump's speech to West Bend, Wis., voters.

Sharpton, who has endorsed Democratic nominee Hillary Clinton, said Trump showed a "complete disregard" for African-Americans when he said the Democratic Party has failed and betrayed black voters. Instead, Sharpton insisted the billionaire businessman's history as a white voter and real estate mogul disabled him from understanding the black community's struggles.

"I don't know what's in his head, but I know where his body has been. And it's been absent in terms of black concerns and black people and black audiences throughout his campaign," Sharpton said. "So either he has no understanding of the issue or he's taking an absolute, adversarial position to where the country's moving, or a combination of both."
