It said on Twitter the incident took place along the White House's north fence line.
"A male subject operating an electronic wheelchair-type scooter lit his outer jacket on fire while sitting along Pennsylvania Ave outside the North Fence Line.
"Uniformed Division Officers immediately responded, extinguished the fire and rendered first aid."
CBS reports authorities searched two bags the man had in proximity to him. It's unclear if they man was trying to make a political statement.
Witness Daniel Kingery told the Daily Mail he believed the incident was politically motivated.
"He wasn't obeying their order to put it down, so it was definitely some sort of a protest."
CNN reports the man did not pose a threat to current US President Donald Trump, who was in the White House that day.
Media were also present inside the West Wing, but were asked to stay inside while the incident took place.
