A security guard who worked for Rep. Jasmine Crockett, D-Texas, was killed in a standoff with Dallas police last week. The guard, identified as Diamon-Mazairre Robinson, was wanted for impersonating a police officer and had a lengthy criminal history, though Crockett said her office could not find any violent offenses in his record. Crockett defended Robinson, saying he never endangered her team and that his death "evokes a range of emotions."

Why it matters

This case highlights the challenges members of Congress face in vetting and securing their own safety, especially with the rise in threats against public officials. It also raises questions about the effectiveness of background checks and security protocols, as well as the need for improved coordination between law enforcement agencies.

The details

Police say Robinson was driving a replica undercover car with stolen government plates, often wore fake police uniforms, and created a fraudulent business where he used fake identifying information to hire legitimate police officers for off-duty jobs. He was also not using his real name, going by the alias "Mike King." Robinson had a lengthy criminal history dating back to 2010, with arrests for offenses such as theft and violating probation.

  • On March 15, 2026, Dallas Police SWAT officers shot and killed Robinson during a standoff.
  • On March 14, 2026, Dallas Police released dash camera footage of the incident at Children's Medical Center Dallas.

What they’re saying

“We are saddened and shocked by some of the concerning revelations. Our team followed all protocols outlined by the House to contract additional security. We were approved to use this vendor who also provided security services for additional entities in the local community and worked closely with law enforcement agencies including Capitol Police.”

— Rep. Jasmine Crockett (Fox News)

“The agencies that he reported to work for do not exist. So dignitaries, basically special dignitary police, that agency does not exist within the federal government. So that's who he portrayed to be. There was no actual federal agency that he worked for that existed. He was very good at hiding his true identity … He had been living like this for many years.”

— William Griffith, Dallas Deputy Police Chief (Fox News)

What’s next

The congresswoman's office says it is conducting a full review of its security protocols and vetting processes to prevent similar incidents in the future.
