The officer who reportedly issued the threat during a Wednesday July 11, 2012 morning roll call in the presence of his colleagues while they discussed threats against the Obamas has been reassigned to the administrative section pending the outcome of investigations.
A senior officer who heard him voice the threat had reported him to their superior.
According the Washington Post, the officer "allegedly said he would shoot the First Lady and then used his phone to retrieve a picture of the firearm he said he would use" to show his colleagues.
Before his redeployment, the officer worked as a motorcycle escort to White House officials and visiting dignitaries.
Reports say the Secret Service is trying hard to downplay the incident.
“Pump the brakes on this one” a Secret Service official told NBC.
"We're aware of it and taking the appropriate steps," another official of the Service told msnbc.com.
The name of the officer who issued the death threat is yet to be released by the Metropolitan Police Department.
There has not been any response from the White House on the incident.
