President Obama's burgerama continues Friday, per CBS News's Mark Knoller.

Knoller tweeted Friday that Obama headed to Five Guys in D.C. with NBC's Brian Williams.

The tweets:
Obama has gone out for lunch - to Five Guys, part of a burger chain with a place near Nats Stadium in southeast D.C.

Could be for the benefit of NBC's Brian Williams, who's taping behind the scenes material for a 2 part prime time special next week.

Yup: Obama ordered a burger for himself and something for Brian Williams and the NBC crew doing 'a day in the life" show (hope Brian pays).

Obama greeting fellow diners at Five Guys - muching on peanuts available to patrons.

Perhaps Obama is also checking out the cyber security conditions at Five Guys. We can't have any hamburger hackers.
