Don Cheadle, Michelle Williams outraged at Trump's Dwyane Wade tweet

Donald Trump is once again igniting outrage with a single tweet.

The U.S.Republican presidential nominee posted a message on social media Saturday morning following the shooting death ofNykea Aldridge, the cousin of NBA star Dwyane Wade.

The initial tweet didn't offer condolences, instead focusing on his bid to win African-American voters in the Nov. 8 American election.

"Dwyane Wade's cousin was just shot and killed walking her baby in Chicago," he wrote after initially deleting the same tweet that misspelled Wade's first name as Dwayne and receiving backlash as a result."Just what I have been saying. African-Americans will VOTE TRUMP!"

Aldridge, a mother of four,died Friday after being caught in cross-fire while pushing a baby stroller in Chicago's South Side near a school where she intended to register her children.

The Chicago Bulls basketball star tweeted about the shooting Friday, calling it "another act of senseless gun violence."

Trump's tweet was slammed as opportunistby many on social media, including Captain America: Civil War and Hotel Rwanda star Don Cheadle.

"You are truly a POS," Cheadle wrote Saturday. In a secondtweet, he said: "Sorry. I misspelled 'die in a grease fire.'"

Michelle Williams, a member of the group Destiny's Child, also responded to Trump's tweet by saying: "An absolute disgrace."

Hours later, the millionaire businessman-turned-politician posted another tweet, this time offering condolences to Wade's family: "They are in my thoughts and prayers."

Trump has been actively trying to win over African-American voters, a demographic that polls show Democratic presidential nominee HillaryClinton as gaining more ground.

Speaking at a rally in Michigan last week, Trump urged black voters to give him a chance.

Earlier this week, Trump referred to Clinton as a "bigot" in an interview with CNN's Anderson Cooper, a tactic also seen by some as a ploy to attractminority voters.
