Two explosive devices were found in mail sent to the offices of former President Barack Obama and former Secretary of State Hillary Clinton, a law enforcement official said Wednesday.
The devices were similar to one found on Monday at the home of the billionaire philanthropist George Soros, the official said.
One device was found on Wednesday morning by a technician who screens mail for the office of Hillary Clinton, a law enforcement official said.
A second similar device was sent to the office of former President Barack Obama.
It was not immediately clear where the devices sent to the Clinton and Obama offices were found.
Mr. Soros’s home is in a suburb north of New York City. That device was constructed from a length of pipe about six inches long filled with explosive powder, and it was “proactively detonated” by bomb squad technicians, according to one of the officials, all of whom were briefed on the investigation.
The motive of the would-be Soros bomber or bombers remained unclear, one of the officials said, adding that there had not yet been any claim of responsibility.
Mr. Soros, who made his fortune in finance and is now a full-time philanthropist and political activist, is often a subject of the ire of right-wing groups. In recent days, some have falsely speculated that he funded a caravan of migrants moving north in Mexico.
