One World's headed by book world superstar Chris Jackson, who also publishes Jay-Z and Ta-Nehisi Coates. He launched One World last year.
Ex-San Francisco 49ers quarterback Kaepernick launched the current movement of NFL players protesting during the national anthem, and he's recently filed a controversial collusion grievance against league owners. He's still looking for a job in the NFL after opting out of his 49ers contract earlier this year.
His campaign began last year, but the issue of NFL player protests has reached a new fever pitch after President Trump weighed in.
Page Six previously reported that Kaepernick had been seen "taking meetings with publishers in the New York offices of WME" to shop the planned book.
