And this is something that they're obviously going to be eager to get to the bottom of. The FBI is working with ATF and Secret Service as well as local law enforcement, as I said. This is something that - this is very much the early stages of the investigations in all three of these cases.

No one has said anything about the motivations of that suspect or anything else. We should emphasize - no one has named any suspect.

But that's a question that people are definitely asking. Again, we don't know at this point in time. And there are questions certainly as to whether there is a political motivation behind this. You know, we are living in very polarized times. And I guess that is one thing that all three of these figures have in common is that they're fairly polarizing figures - Soros, as well as Hillary Clinton and President Obama. There's all kinds of conspiratorial speculation about George Soros. INSKEEP: Social media has connected him with no evidence whatsoever to this caravan moving up from Central America. LUCAS: That's probably the simplest way of putting it. Certainly a lot of questions as to the motivations behind whoever left it, particularly since Soros has been kind of the target of a lot of rhetoric from people kind of on the far-right who accuse him of, you know. This is another thing that the FBI and local law enforcement in New York are investigating. But, you know, it's unclear what the motive of the individual who left this this device may have been. That was - a pipe bomb was found in the mailbox of Soros' home in a suburb of New York. Which brings us to this other threat, something was discovered being sent to George Soros. INSKEEP: You've added something meaningful here because there are a lot of different things that could be in a suspicious package, I'm sorry to say, but they're saying potential explosive devices, a particular kind of threat here. The Secret Service is working with the FBI, with the Bureau of Alcohol, Tobacco, Firearms and Explosives, as well as state and local law enforcement to try to figure out as much as they can. They weren't in their hands, they weren't in their houses, but they were addressed to them. They say that neither Clinton nor Obama ever received the packages. And what the Secret Service is saying is that both packages were immediately identified during routine screening as potential explosive devices. INSKEEP: Oh, the former president has a home here in Washington now. And then early this morning, the Secret Service intercepted a second package that was addressed to Barack Obama here in Washington, D.C. One was addressed to Hillary Clinton at her home in Westchester County, N.Y. And what they are saying is that the Secret Service intercepted two suspicious packages. They have sent out a statement at this point. And this is something that really is just breaking news. LUCAS: Well, they aren't saying a whole lot right now. INSKEEP: How much is the Secret Service saying? And we're going to bring you up to date on what we do know with NPR justice reporter Ryan Lucas. We should emphasize at this moment we don't know much about the seriousness of this story, but we do know that it's happening. And that news comes after a bomb was apparently sent to the home of the financier George Soros. The source of that news is the Secret Service. Someone sent some suspicious packages to former President Obama and former Democratic presidential nominee Hillary Clinton.
