3:42 PM PT -- Stephen Jackson just made a promise to George Floyd's family -- that he will step in and do everything he can to be a father figure for George's 6-year-old daughter.
"I'm gonna be there for her," Jackson said to Floyd's family Tuesday in Minneapolis. "I'm gonna walk her down the aisle. I'm gonna be there for her. I'm gonna be here to wipe your tears. I'm gonna be here for you and Gigi."
"Floyd might not be here but I'm here for her, I'm here to get justice."
"This sh*t has to stop."
Ex-NBA star Stephen Jacksonis now putting pressure on his fellow pro athletes in the NFL, NBA and MLB to call out the people in the front offices ... claiming straight up, "They're not fighting for us!"
"It's time to hold our owners, GMs, Vice Presidents, everybody at the top accountable," Jackson said on social media.
"They want you to dance They want you to smile, promote, shoot, workout, represent the organization the right way, right? But they're not fighting for us! I don't hear none of them."
Jackson has been speaking out publicly -- and passionately -- ever since the killing of his longtime friend George Floyd ... demanding justice and action.
While he doesn't call anyone out by name -- it's clear Jackson feels the people at the top of the organizations are not doing enough to support the movement against police brutality, racism and social injustice.
"It's time to hold them accountable, bro. Hold ya'll [Team President] accountable. Hold ya'll owner accountable because 9 out of 10 times, if they ain't speaking with us, then they against us."
"They love you bringing all that money in, but why they ain't speaking up when our kids get murdered or when our black men or black women getting murdered?"
