Washington lobbying firm Federal Advocates was among the schools and businesses around the country targeted in a wave of bomb threats on Thursday.

Michael Esposito, the president of the firm, received an email Thursday afternoon threatening to detonate a bomb in the firm’s building on K Street unless he paid $20,000 in bitcoin by the close of the day, according to a copy seen by POLITICO.

The firm said in a statement that it notified the authorities and evacuated its office.

Police in Washington said Thursday the threats aren’t considered credible.

“Each of the threats were received via email requesting bitcoin ransom and to our knowledge, no one has complied with the transaction demands,” the Metropolitan Police Department said in a statement posted to Twitter.

The email received by Federal Advocates appeared similar to one sent to businesses in Cedar Rapids, Iowa, and posted on Facebook by police there.

“I want to propose a deal,” the email received by Esposito stated, warning that an explosive device had been hidden in the building. “You pay me 20.000 $ in Bitcoin and the device will not detonate, but do not try to fool me -I warrant you that I have to withdraw my mercenary only after 3 confirmations in blockchain network.”

Federal Advocates represents a variety of clients, including PetSmart and the city of Richmond, California.

Nick Tobenkin, a Federal Advocates lobbyist, said in a statement that the firm would not “be intimidated by threats and will continue to serve our clients.”
