President Trump on Monday bashed Chicago Mayor Brandon Johnson (D) as “incompetent” amid threats from Trump to send National Guard troops into the Illinois city.

“The incompetent Mayor of Chicago just stated that, in DC, where crime has been brought down to almost nothing, there have been no murders in 9 days, something which hasn’t happened in years, and people are safe again, only nine people have been arrested,” Trump said on Truth Social. “That is wrong, hundreds of criminals have been held, captured, and arrested, and their guns have been taken away. DC IS SAFE AND BOOMING!!!”

As of Sunday, there have been over 910 total arrests in Washington, D.C., and 101 firearms have been seized since federal law enforcement was sent into the nation’s capital on Aug. 7, according to the White House. On Saturday night alone, there were a total of 93 arrests and six illegal firearms seized, the White House said.

Johnson on Sunday said Chicagoans will “not bend or cower” to Trump’s threats to turn a federal policing push next to Baltimore and Chicago, cities like D.C. that are overwhelmingly blue and represented by Democratic mayors.

The mayor said he is in “active communication” with local and state counterparts “as we prepare for any potential unconstitutional military deployments to Chicago.”

On Friday, Trump told reporters, “I think Chicago will be … next.”

The Washington Post reported on Saturday that the Pentagon for weeks has been planning a military deployment to Chicago.
