Federal law enforcement agencies are closely monitoring potential threats related to the upcoming memorial for Charlie Kirk in Glendale, Arizona, scheduled for Sunday. A new assessment indicates that officials are tracking several threats of unknown credibility against attendees, including former President Donald Trump, Vice President JD Vance, and members of the Kirk family.

The memo, issued by agencies such as the FBI, Department of Homeland Security (DHS), Secret Service, and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), warns that violent extremists and lone offenders may target the memorial due to the presence of high-profile individuals and the significant media attention surrounding the event.

DHS has classified the funeral as a Special Event Assessment Rating (SEAR) Level 1 event, which means it will receive the same level of security as major events like the Super Bowl or the Boston Marathon. Despite the heightened security measures, federal agencies have stated there is no verified, credible plot against the event. However, they are responding to unverified threats and recent incidents of political violence, particularly in Arizona.

William Mack, the Secret Service special agent in charge of the Phoenix field office, confirmed that the Secret Service is coordinating security for the funeral. "Our teams are already on the ground in Phoenix and Glendale, working side-by-side with state, local, and federal partners," Mack said. "Together, we are fully committed to ensuring that these solemn events receive the comprehensive protection and support they require."

Local law enforcement, including the Glendale Police Department, is also preparing for a large turnout. Public information officer Jose Santiago noted that they anticipate over 100,000 attendees, with people traveling from across the country. He mentioned that attendees might start lining up as early as 2 a.m. on Sunday, with parking opening at 7 a.m. Camping in the area will not be permitted.

Santiago emphasized the extensive security presence, stating, "Officers will be anywhere the eye can see, and in places it can't," referring to the use of aircraft, drones, and helicopters. The Department of Public Safety and Secret Service will manage security inside State Farm Stadium.

Derek Mayer, a former assistant special agent in charge of the Secret Service's Chicago field office, explained that the SEAR designation allows for a coordinated response from various agencies. "This designation allows for a 'whole of government' approach, which means many different local, state, and federal agencies will supply resources and manpower to guarantee extra security measures are in place," Mayer said.

The memorial is open to the public, but attendees are encouraged to register in advance.
