The war of words between Donald Trump and Democratic Gov. Wes Moore of Maryland escalated Sunday with the president threatening to send National Guard troops to Baltimore to attempt to reduce crime, and the first-term governor suggesting Trump was peddling outdated racist tropes he referred to as “blissful ignorance” to score political points.

The Trump administration has been planning for weeks to send the National Guard to Chicago, two officials told CNN, as President Donald Trump looks to expand his anti-crime agenda and crackdown on immigration in major cities across the United States.
