After surprising students at Stoneman Douglas High School and speaking with them on Wednesday, Dwyane Wade tweeted that he’s “looking forward to being more involved in the change that they WILL create.”

A few days later, Wade announced that he and Gabrielle Union will be donating $200,000 on behalf of Chicago to the March for Our Lives fundraiser. Marches will take place in Washington, D.C., and other cities around the country on March 24 “to press their demands for safer schools and for legislation ‘to effectively address the gun violence issues that are rampant’ across the nation, per USA TODAY.

The movement was started by Stoneman Douglas students after a gunman killed 17 people at their school in Parkland, Florida, on Valentine’s Day.

“(Carmelo Anthony and I) both come from communities where gun violence is an every day (occurrence),” Wade wrote.”Enough is enough! … They need our help! I’m asking my NBA fam to join us in raising money to send kids from undeserved communities to march.”

The GoFundMe for the fundraiser Wade is promoting says half the money raised will go to the March For Our Lives Action Fund to cover costs of organizing the D.C. march, and the other half will go to the Broward Education Foundation to help victims and families affected by the Parkland school shooting.

Shortly after Wade’s tweets, Carmelo Anthony said he’ll be giving to the community and students in Baltimore, and he added that the NBA Players Association Foundation will match up to $25,000 of player donations.

Wade has also dedicated his season to Joaquin Oliver, who was one of the 17 people killed in the Parkland school shooting, after he found out Oliver was buried in his Heat jersey.
