House Republicans are establishing a special task force to investigate allegations that U.S. Central Command's top intelligence officials pressured analysts to discard parts of their reports that reflected poorly on the war effort in Iraq and Syria.

Three committees announced Friday that the task force will produce preliminary results early next year. Republican Reps. Ken Calvert of California, Mike Pompeo of Kansas and Brad Wenstrup of Ohio will lead the investigation.

The Pentagon's inspector general is investigating the allegations of intelligence puffery.

A former Central Command official said more than 50 intelligence analysts had complained that their conclusions were undercut. One or more senior analysts from the command made a written complaint to the Defense Department inspector general in July, prompting an investigation that officials have publicly acknowledged.
