L.A. Police Department and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives are on the scene and plan to deploy a robot to examine the package, the San Diego Union-Tribune reported.

Earlier on Wednesday, a suspicious package addressed to Waters was intercepted in a Maryland mail screening facility.

“In addition to the five packages referenced in our earlier statement, we have now confirmed two additional packages, both addressed to Rep. Maxine Waters, that are similar in appearance,” the FBI confirmed in a tweet Wednesday evening.

Waters is a vocal critic of President Trump.

Several suspicious packages and “potential explosive devices” were found this week outside the homes and offices of Democratic politicians. It was not immediately clear if this one was related.

On Monday, an explosive device was found outside Democratic donor George Soros’ home, on Tuesday a potential explosive device was found outside Bill and Hillary Clinton’s residence, and on Wednesday outside former President Barack Obama’s home in Washington, D.C.

Suspicious packages were also sent to the offices of Democratic Rep. Debbie Wasserman Schultz, of Florida, and Sen. Kamala Harris, of California.

CNN’s offices in New York were evacuated Wednesday morning after a suspicious package addressed to former CIA Director John Brennan was intercepted.
