A Republican mayor from Mississippi is resisting calls to resign following a series of tweets in which he claimed he “didn’t see anything unreasonable” about the brutal death of George Floyd, an unarmed black man, at the hands of a white police officer who kneeled on his neck until he could not breathe anymore.

Petal Mayor Hal Marx tweeted Tuesday that he didn’t understand why “anyone in the world” would choose to become a police officer on the same day four Minneapolis Police Department police officers were fired for their involvement in the incident.

Marx followed up his tweet directly referencing Floyd’s death.

“If you can say you can’t breathe, you’re breathing. Most likely that man died of overdose or heart attack. Video doesn’t show his resistance that got him in that position. Police being crucified,” Marx tweeted.
