Now Nike has added him to a line-up of athletes to feature in a new ad campaign to mark the 30th anniversary of its "Just Do It' slogan".
The quarterback appears alongside the message: "Believe in something".
On Tuesday afternoon, President Trump weighed in. As expected, there is now a whole slew of social media posts featuring people dramatically burning their sneakers, blowtorching their clothes, throwing Nike items into the trash, and cutting up their socks.
Nike's new ad campaign not only featured the footballer but also hinted at Kaepernick's political stand with their tagline: "Believe in something".

Critics have burned Nike trainers and clothing in protest at the decision to use Kaepernick in the campaign. "Even if it means sacrificing everything" above the trademark Nike swoosh. The NFL team owners passed a rule this offseason that gives players who would kneel the option of remaining in the locker room during the anthem.

Kaepernick, who filed a grievance in October 2017 against the NFL, last played in the league during the 2016 season for the San Francisco 49ers.
