WASHINGTON (AP) — A U.S. official says a “functional explosive device” was found at Hillary and Bill Clinton’s suburban New York home, and another at the home of former President Obama.

The official says investigators believe the explosive is linked to one found Monday at the compound of liberal billionaire George Soros.

The official wasn’t authorized to publicly discuss an ongoing investigation and spoke on condition of anonymity.

Neither Obama nor Clinton received the packages or were at risk of receiving them, the Secret Service said. They were discovered during “routine mail screening procedures as potential explosive devices and were appropriately handled as such,” the agency said in a statement.

The package intended for Obama was intercepted in Washington, DC, on Wednesday morning, and the one intended for Clinton was addressed to her in Westchester County, New York, on Tuesday.

The device was discovered early Wednesday morning at the Clinton’s home in Chappaqua, New York.

Police in New Castle, New York, who cover Chappaqua, say they assisted the FBI, Secret Service and Westchester County authorities in “the investigation of a suspicious package.”
