In an interview with ABC's "Good Morning America" that was to air in full Friday morning, Wade said he was "grateful that it started a conversation."
"But on the other hand, it just left a bad taste in my mouth because of what my family is dealing with and what our city of Chicago is dealing with and it looks like it's being used as political gain," Wade said.
On Aug. 27, the GOP presidential nominee tweeted, "Dwyane Wade's cousin was just shot and killed walking her baby in Chicago. Just what I have been saying. African-Americans will VOTE TRUMP!"
Trump later offered his condolences.
"My condolences to Dwyane Wade and his family, on the loss of Nykea Aldridge," another Trump tweet read. "They are in my thoughts and prayers."
Authorities say Nykea Aldridge, 32, was killed when two men walked up and fired shots at a third man on Chicago's South Side at about 3:30 p.m. on Aug. 26. Police say Aldridge, who was pushing a baby in a stroller, was not the intended target.
Chicago police have charged brothers?Darwin and Derren Sorells with first-degree murder in Aldridge's death.
Derren Sorells, 22, is a documented member of the Gangster Disciples and currently is on parole, according to Chicago Police spokesman Anthony Guglielmi. Darwin Sorells, 26, also is on parole for a gun charge, according to Guglielmi.
Wade, who returned to his hometown by signing last month with the Bulls, and his mother both were part of a series of panel discussions on gun violence hosted a day earlier by The Undefeated on ESPN. Wade grew up in a South Side Chicago house headed by his mother, who was then a drug dealer. Jolinda Wade gave up drugs and turned her life around after being released from prison in 2003.?
Chicago has been hit hard by violence this year. More than 2,600 people have been shot in the city, mainly on the South and West sides.

Its murder rate is higher than that of New York and Los Angeles.
