The venue made it checkable. Speaking at the rescheduled White House Correspondents' Association dinner at the Waldorf Astoria on Friday July 24, the president described Washington as 'almost a crime-free city' and claimed an 88 percent reduction in crime [1].
The Metropolitan Police Department publishes its running totals on a public page. As of that same day, July 24, total violent crime in 2026 stood at 1,512, against 1,478 at the same point in 2025 - an increase of 2 percent [2].
Violent crime is the category the federal intervention was sold on, and it is up [2].
All crime is down 20 percent, at 11,334 against 14,137 [2]. That is a genuine and substantial decline, worth stating plainly rather than burying: crime overall in the District is meaningfully lower than a year ago. It is not 88 percent lower - the claimed figure overstates the real decline by more than a factor of four [1][2].
Homicides are down 37 percent, from 92 to 57 [2] - the strongest number in the set, and one that could have been cited accurately.
MPD notes its data are preliminary and subject to reclassification [2], the ordinary caveat on a live dashboard, which cuts both ways. What it does not do is turn a 20 percent decline into an 88 percent one, or a 2 percent rise in violent crime into a crime-free city.
