(CNN) Democratic Rep. Maxine Waters of California was the intended recipient of a suspicious package intercepted at a congressional mail sorting facility outside Washington, according to two sources.

Later on Wednesday, a spokesperson for the Bureau of Alcohol, Tobacco, Firearms and Explosives, Ginger Colbrun, said a second package addressed to Waters had been found at a postal facility in south central Los Angeles. Colbrun told CNN the package matches the description of those sent to CNN and Democratic political figures. The Los Angeles Police Department said the postal facility was evacuated while an investigation takes place.

The packages addressed to Waters, a liberal firebrand and the top Democrat on the House Financial Services committee, had similarities to the other suspicious packages, according to two law enforcement sources. One source said that belief was based on the timing, packaging and devices inside the packages. It was not clear if it was capable of exploding.

"I have been informed by U.S. Capitol Police that my Washington, DC office was the target of a suspicious package that has been referred to the FBI," Waters said in a statement following the discovery of the first package. "I am appreciative of the law enforcement entities who intercepted the package and are investigating this matter. I unequivocally condemn any and all acts of violence and terror."

Capitol Police said their offsite mail screening facility was evacuated as a precaution following the identification of a suspicious package addressed to a member of Congress. Capitol Police did not identify Waters as the recipient of the package. Capitol Hill's law enforcement arm said it was working with the FBI on investigating the incident.
