WHITE SUBSTANCE AT OBAMA DC OFFICE

WASHINGTON - The Secret Service is investigating after reports that a white powdery substance had been found at former President Barack Obama's D.C. office.

The incident was reported Tuesday around 12:30 p.m. at the World Wildlife Fund Headquarters in Northwest D.C., where the former president has leased office space since leaving office in January 2017.

D.C. Fire and EMS Battalion Chief Edward Smith tells FOX 5 a letter was mailed to the West End office from Hong Kong, and reportedly contained baby powder. Authorities say had no return address.
