A second suspicious package addressed to Maxine Waters was identified Wednesday in Los Angeles after Capitol Police investigated a potential explosive device at a House of Representatives mail screening facility earlier in the day.

Waters, a California Democrat, said in a statement earlier in the day that her Washington office, was the target of a suspicious package.

The second package has similar markings and characteristics to five others sent to prominent Democrats and CNN this week, according to an Associated Press report. Packages, mailed in manila envelopes with Forever stamps were sent to George Soros, Hillary Clinton, Barack Obama, John Brennan and Eric Holder. The package intended for Holder did not reach its intended destination, but was rerouted to the return address, of Rep. Debbie Wasserman Schultz’s district office in Florida.

On Wednesday afternoon the FBI said that it was possible that additional packages were mailed to other locations and that the public should “remain vigilant and not touch, move or handle any suspicious or unknown packages.”
