President Donald Trump just took a cheap shot at an NFL player who dared to speak his mind.

During a rally in Louisville, Kentucky, on Monday, the commander in chief brought up free agent quarterback Colin Kaepernick s inability to land a job with a team , according to reports .

Trump once called Kaepernick disrespectful for taking a knee during the national anthem to protest racial injustice before games last season a move that polarized the nation. This time, the president referenced a Bleacher Report story in which an unidentified team general manager estimated that 10 percent of teams were reluctant to sign the former 49er over fears Trump would tweet about them.

There was an article today that NFL owners dont want to pick him up because they dont want to get a nasty tweet from Donald Trump , the president said. Do you believe that?

I said, If I remember that one, Im gonna report it to the people of Kentucky because they like it when people actually stand for the American flag.
