During a speech in Chicago to police brass from across the US, Donald Trump attacked the city's police chief who is boycotting the visit from the president, who used his address to law enforcement to blame so-called "sanctuary" cities for violent crime rates.
Mr Trump accused Chicago Police Chief Eddie Johnson of "not doing his job" in a city that the president has often ridiculed as a "war zone" for its high murder rate. There have been 425 homicides in Chicago so far this year.
He also said Chief Johnson is putting "criminals and illegal aliens before the city of Chicago" and that "sanctuary" cities are knowingly releasing jailed immigrants accused of violent crime.
His appeal to law enforcement arrived that morning after he was roundly booed during Game 5 of baseball's World Series in DC on Sunday, with fans of the Washington Nationals and Houston Astros chanting "Lock him up!" as "Veterans for Impeachment " signs were held aloft by spectators, prompting the president to leave the stadium early.
His unwelcome appearance at the game followed what should have been a triumphant moment for his administration in the announcement of the death of Isis leader Abu Bakr al-Baghdadi during a US-led raid that saw the terror group leader cornered in a dead-end tunnel in Syria. The president assured the world the terrorist had died "crying and screaming".
In a Monday press conference, the president's Chairman of the Joint Chiefs of Staff Mick Milley said he doesn't know where Mr Trump got that account of the operation.
The president shared a photo on Twitter of an Army Delta force dog that was critical in the operation, according to Mr Trump. The dog's name is still classified. General Milley said it returned to its military unit.
When leading Democrats Nancy Pelosi and Chuck Schumer demanded to know why Congress had not been briefed on the operation in advance at a time when the White House's approach to foreign policy is already under intense scrutiny, vice president Mike Pence squirmed and struggled to answer the question on Fox News.
Mr Trump later explained that the administration was going to notify Congress but "we decided not to do that because Washington leaks like I've never seen before. There's no country in the world that leaks like we do, and Washington is a leaking machine."
