(Washington Times) Congressional leaders are calling on Attorney General Eric H. Holder Jr. and FBI Director Robert S. Mueller III to explain why their agencies kept information about former CIA Director David H. Petraeus‘ extramarital affair from the White House, Congress and the U.S. intelligence community as the scandal expanded and ensnared the top U.S. commander in Afghanistan.

Lawmakers also said they intend to call on Mr. Petraeus to testify about the terrorist attack on the U.S. Consulate in Libya as soon as this week.

The Pentagon inspector general Tuesday opened an investigation of Marine Gen. John Allen after the FBI found “inappropriate” emails among tens of thousands he had sent to a Florida socialite during a cybercrime probe that uncovered Mr. Petraeus‘ affair and forced his resignation last week.
