The post seems to have been deleted, but why not still check the claim?
It appears to be a relatively popular version of events spread by Newsmax host Greg Kelly, and was repeated by Trump on "Rob Schmidt Tonight", according to an article published by Newsmax. By the same article's own admission: "several police officers who had served at the Capitol on Jan. 6 also died in the days and weeks that followed." Presumably, the context they're leaving out there is "...from the injuries they sustained during the events at the Capitol".
This context can be found in the Capitol Police's press release:
"At approximately 9:30 p.m. this evening (January 7, 2021), United States Capitol Police Officer Brian D. Sicknick passed away due to injuries sustained while on duty. Officer Sicknick was responding to the riots on Wednesday, January 6, 2021, at the U.S. Capitol and was injured while physically engaging with protesters."
This is not to mention at least two officers who died by suicide following the events of January 6, as covered by Politico. According to Acting Metropolitan Police Chief Robert Contee, “...they took their own lives in the aftermath of that battle.”
While I think Trump or Kelly could perhaps argue that there was only one person who died directly from physical violence on the day of January 6th (and even then, they'd be splitting hairs), they don't seem interested in making that caveat.
