The fracas took place while the Obama’s were at dinner celebreating Michelle Obama’s birthday.
The Secret Service was responding Tuesday night to an escalating protest that may have involved one or more smoke bombs being thrown over the White House fence.
An estimated 1,000 protesters have gathered. No arrests have been made, but authorities are on alert.
The Secret Service also deployed a robot to check out the devices on the North Lawn. No one is currently allowed to leave through the North Gate, but those with the right access can go through the White House and leave through the South Gate.
The tense scene outside the White House follows an earlier protest on the West Lawn of the Capitol, in which several hundred protesters affiliated with the Occupy Wall Street movement decried the influence of corporate money in politics and voice myriad other grievances.
Organizers had touted the rally, known as Occupy Congress, as the largest national gathering of Occupy protesters to date and secured a permit that would have allowed up to 10,000 people to participate. By mid-afternoon, the protest appeared to have fallen far short of those goals.
There were four arrested at the Occupy Congress protest earlier in the day.

Four people were arrested as hundreds of protesters from the Occupy movement gathered Tuesday on the west lawn of the Capitol, chanting, singing, marching and disrupting congressional offices throughout the day.
At mid-afternoon, dozens swarmed into the Rayburn and other House office buildings, waving banners and chanting, “We are the 99 percent!” At 6:30 p.m., the group began marching from the Capitol to the Supreme Court to the White House, and organizers said they expected “many” to be arrested.

Organizers had hoped thousands would come for Tuesday’s event. In the end, it was more like 500 — riding buses and hitching rides from cities including Orlando, Nashville, Los Angeles and New Haven, Conn. The number swelled to about 1,000 when night fell.
