WASHINGTON -- Acting CIA Director Michael Morell is holding meetings on Capitol Hill to explain the CIA's take on events that led David Petraeus to resign last week after acknowledging an affair. Congressional aides say he met with Senate Intelligence Chairman Dianne Feinstein and the committee's senior Republican, Sen. Saxby Chambliss, on Tuesday and will meet the heads of the House Intelligence Committee on Wednesday. FBI Deputy Director Sean Joyce is also scheduled to brief members Wednesday. Lawmakers are concerned whether Petraeus biographer Paula Broadwell had unauthorized access to classified information. The aides spoke on condition of anonymity because they were not authorized to confirm the sensitive meetings publicly.
