President Donald Trump's border chief vowed Thursday to press on with the federal immigration crackdown in Minneapolis while acknowledging the mission needed to improve and promising to hold agents to account. The border czar called on Minnesota's residents to turn down the temperature and stop what he called the "hateful rhetoric" being used against federal agents carrying out immigration raids. Homan said any federal agents who breach codes of conduct "will be dealt with". Two American citizens, Renee Good and Alex Pretti, demonstrating against the sweeps have been shot dead by federal agents. But the president on Wednesday accused the city's mayor, Jacob Frey, of "PLAYING WITH FIRE" for refusing to rally local police to enforce the federal immigration sweeps.
