WASHINGTON: As lawmakers prepare to debate intelligence legislation, Democrats are accusing senior CIA officials of repeatedly misleading Congress.

Republicans charge the timing of the allegations and a threat from President Barack Obama to veto the intelligence bill are just political maneuvering to protect House Speaker Nancy Pelosi.

Letters by the chairman of the House Intelligence Committee and other members of the panel say CIA Director Leon Panetta told Congress last month that senior CIA officials have concealed significant actions and misled lawmakers repeatedly since 2001.
