Defensive coordinator Jack Del Rio is under fire ... so much so that some of his critics are calling for his firing.

The Washington Commanders assistant has apologized for calling what happened on January 6 at the Capitol building in Washington D.C. a "dust-up" while answering questions from media members following Wednesday's OTA practice session.

On Thursday and then Friday, in addition to Del Rio issuing an apology, he was fined by head coach Ron Rivera.

NAACP president Derrick Johnson called Del Rio's attitude "twisted," saying, "You can't coach a majority-Black team while turning your back on the Black community." It's time to go."

Rivera met with Del Rio to discuss his Wednesday comments. "His words don't reflect the organization's views and hurt the DMV community. As a U.S. citizen, he can speak out. His statements upset many in our community."

Doug Baldwin: "Jack Del Rio is clueless. So far, so loving and considerate. Protesting a murder is different from plotting a coup after losing an election. Let's not equate this with vandalism."

From Brian Mitchell, the former Washington standout: “You got all these issues going on with the Washington Commanders right now, and [Del Rio’s] constantly trying to make waves because of stupidity.

Rivera's statement included the note that the Washington Commanders' fine of Del Rio will be donated to the United States Capitol Police Memorial Fund.
