A newly surfaced video appears to show Diamon Robinson, the man who worked on Rep. Jasmine Crockett’s security detail under the name “Mike King,” helping two other guards forcibly remove and assault two brothers at a public swearing-in ceremony last year. The brothers say the confrontation erupted after they tried to serve legal papers inside Fair Park’s Hall of State. The clip is now fueling fresh questions about how Robinson was screened for protective work, just as investigators and local outlets continue to analyze body-camera footage from a March standoff that ended in his death.
Video purports to show Fair Park removal
The recording, described and published by local reporters who reviewed it, shows Robinson and other men grabbing JJ and Lamar Jefferson and dragging them out of the event, according to CBS News Texas. JJ Jefferson told the station, "You shouldn't be assaulted while trying to exercise a lawful service," and said officers at the scene told him they could not step in. The brothers say their earlier complaints went largely nowhere, a claim that has resurfaced as Robinson’s work around elected officials comes under renewed scrutiny.
Bodycam released, officers describe standoff
Dallas police have released edited body-worn camera footage that shows officers chasing Robinson from downtown into the Medical District and then confronting him in a hospital parking garage. There, SWAT officers used tear gas before the shooting, as reported by The Dallas Morning News. Authorities say Robinson, publicly known as Mike King, was wanted on active warrants and that investigators recovered multiple firearms and fake law enforcement credentials during searches. The Dallas County district attorney's office and the police department's special investigations unit are now reviewing the officer-involved shooting.
Campaign filings and off-duty hiring questions
Federal campaign filings show a small payment to a “Mike King” for security services in March 2025, and local reporting indicates investigators are examining Robinson’s use of off-duty hiring platforms that placed real officers on private details, according to NBC DFW. Police officials say the situation exposed gaps in how outside coordinators are vetted and has prompted a review of the systems used to schedule secondary jobs for officers. Those platform records and payment entries have become part of the broader questions over who approved Robinson for protective roles in the first place.
Calls for outside review
JJ and Lamar Jefferson say they now want the Department of Justice to investigate other members of Crockett’s security team and to look at whether police failed to properly pursue their assault claims, the brothers told CBS News Texas. Dallas police declined to comment about the earlier Fair Park incident and, according to the station, referred some questions to the U.S. Capitol Police. Crockett's campaign has said it followed House hiring protocols and has expressed sorrow over the unfolding revelations, according to The Dallas Morning News.
