Secretary of Homeland Security Alejandro Mayorkas traveled to Los Angeles this week to review security preparations for the Super Bowl, which will be held on Sunday.

The Department of Homeland Security is working with local law enforcement to provide operational and technical support to the NFL and California, Mayorkas said in a release on Feb. 9.

"The Department of Homeland Security is fundamentally a department of partnerships, and those partnerships are critical to ensuring the safety and security of Super Bowl operations as well as that of the surrounding community," Mayorkas said.

Each year, the Super Bowl is reviewed by the DHS for a risk assessment, the DHS reported in the release. This year's game was classified as a Special Event Assessment Rating Level 1, meaning it's considered a significant event requiring a large amount of federal support.

Various DHS agencies and over 500 personnel will be monitoring the event to secure its safety and security, the DHS reported. Security resources will include air and maritime support, human-trafficking prevention, and several weapon-detection technologies.

In partnership with the NFL, the DHS also highlights the "If You See Something Say Something" campaign, which emphasizes to the public the significance of reporting any suspicious activity.
