(CNN) – Mitt Romney received his second intelligence briefing Thursday at an office building in Herndon, Virginia, an outer suburb of Washington.
Romney's first briefing came September 17 at an FBI building in Los Angeles, less than one week after criticizing President Barack Obama over the attacks on U.S. diplomatic posts in Egypt and Libya.

Romney's team did not say who in the national intelligence community provided the briefing.
The briefings are a customary measure in the latter stages of a general election campaign for presidential challengers, regardless of which party is in power.
Michael Steel, a spokesman for GOP vice presidential nominee Paul Ryan, confirmed Thursday that Ryan had also received an intelligence briefing, first reported by ABC News, though declined to provide further details.
