Arizona DPS director tweets response to Nike's Kaepernick ad

PHOENIX (KSAZ) - The director of the Arizona Department of Public Safety tweeted a response to Nike's ad campaign featuring former NFL quarterback Colin Kaepernick.

On Wednesday night, Col. Frank Milstead tweeted out an image of slain DPS Trooper Tyler Edenhofer with the words, "Believe in something. Even if it means sacrificing everything."

Trooper Edenhofer died after being shot on July 25 during a roadside confrontation with a suspect on Interstate 10. Edenhofer was in the last week of his training when he was shot.

The words in Milstead's tweet are the same that appear Nike's new ad campaign with Kaepernick.

Also on Wednesday, Kaepernick tweeted out a video featuring fellow athletes Serena Williams and LeBron James that is part of the new Nike "Just Do It" campaign.

The video will also be shown during the regular-season debut of "Thursday Night Football."

President Donald Trump has been highly critical of the new ad campaign, saying Nike is getting "killed" over its endorsement deal with Kaepernick.

Kaepernick last played for the San Francisco 49ers in 2016. He has since filed a grievance against the NFL, claiming NFL owners conspired to keep him out of the league because of his protests of social injustice.
