Police are investigating a white substance that was sent to former President Obama's office in DC.
The letter had no return address but reportedly originated from Hong Kong. Obama leased an office in the building after leaving the White House in January 2017. The incident called for FBI, Secret Service, police, and fire crews to rush to the scene. The non-profit World Wildlife Fund owns the building and also has its headquarters there.
The Obama family lives in D.C.'s Kalorama neighborhood which is near the office. It reportedly contained baby powder.
There is no indication if Obama was at the office at the time the package was discovered. It's unclear if Obama was in the office.
His wife, Vanessa Trump, was rushed to hospital after she opened the letter, that contained a threatening note that read: "You're an terrible person and now you get what you deserve".
Suspect packages containing white powder have been sent to the addresses of several high profile figures in recent days.
It comes just a day after Donald Trump's daughter-in-law was taken to hospital a letter containing a "suspicious substance' was sent to her NY apartment".
Brendan Rohr, a spokesman for WWF, told The Hill that the building returned to normal operations after authorities determined that the substance was not harmful.
