Barack Obama safely made it through eight years in office but had an incident Tuesday that could be cause for alarm.

The Secret Service is investigating a white powdery substance found at Obama's Northwest Washington, D.C., office, according to FOX D.C. He has been leasing the office space since he left the White House in January 2017. The substance was reported on Tuesday around 12:30 p.m. at the World Wildlife Fund Headquarters. 

D.C. Fire and EMS Battalion Chief Edward Smith confirmed that a letter was mailed to the West End office from Hong Kong with no return address.

It isn't known whether Obama, who currently lives with his family in the Kalorama neighborhood, was present in the office at the time of the reported incident. 

Similar incidents involving powder have recently occurred, including a “suspicious package” found in a Palace of Westminster office and an incident involving President Donald Trump's daughter-in-law Vanessa Trump (Donald Trump Jr.'s wife), who opened a white envelope containing white powder, which was later confirmed to be cornstarch. 

We'll definitely keep our eyes and ears peeled for more updates.
