There is an internal investigation by the Central Intelligence Agency that has found that its officers have been improperly penetrating computer networks used by the Senate Intelligence Committee.
The report found that C.I.A. officers created fake online profiles to gain access to computers used by members of the committee staff. They tried to stay undercover as they hovered around the system and the network.
C.I.A. spokesman John O. Brennan released a statement Thursday morning where he apologized to the two senior members of the intelligence committee. He also said he would set up an internal accountability meeting to review the circumstance.
The Justice Department has declined to investigate the situation. The C.I.A. statement barely gave any details about the report findings.
