Former CIA director John Brennan, now an MSNBC commentator and frequent critic of President Donald Trump, praised former quarterback Colin Kaepernick for his new Nike campaign.

“Well done, Colin, well done,” he wrote approvingly on Twitter Monday evening to the athlete who once wore socks to football practice that portrayed police officers as pigs.

Kaepernick launched his new Nike campaign on Labor Day, asserting that he sacrificed his football career for his right to kneel during the national anthem.

Kaepernick has not played football since the 2016 season after he lost the starting job as quarterback for the San Francisco 49ers to Blaine Gabbert.

Brennan praised Kaepernick for his protest, asserting that it brought attention to “racial injustice” in America.

“He did so not to disrespect our flag but to give meaning to the words of the preamble of our Constitution — “in order to form a more perfect union,” he insisted.

Colin Kaepernick drew our collective attention to the problem of continued racial injustice in America. He did so not to disrespect our flag but to give meaning to the words of the preamble of our Constitution—“in order to form a more perfect union.” Well done, Colin, well done. https://t.co/4ALyUxLjM5 — John O.

Kaepernick’s protest was also praised by former Iranian dictator Mahmoud Ahmadinejad.
