Story highlights Report alleges a civilian Defense Intelligence Agency analyst said intelligence was altered to seem better for the U.S.

Central Command said the intelligence community incorporates a variety of viewpoints in its analysis

Washington (CNN) The Defense Department's inspector general is believed to be reviewing an allegation that U.S. intelligence gathered on ISIS was altered, an official told CNN Wednesday, after The New York Times reported that the IG might be looking into whether intelligence reports about the terror group were amended.

A U.S. defense official told CNN it is believed the inspector general is looking into some question on ISIS intelligence, but the Pentagon said it cannot comment on IG matters because that organization operates independently of the Pentagon and the department has no knowledge of what it is doing.

The response came after a Times report late Tuesday that at least one civilian Defense Intelligence Agency analyst said he had evidence that showed that individuals at U.S. Central Command were adjusting intelligence reports for top officials -- including President Barack Obama -- to enhance the amount of progress the United States had made in fighting ISIS.

The Times cited several officials familiar with the matter to say the inspector general's office had opened an investigation into the allegations but more details weren't available.

In a statement, CentCom said it could only describe the intelligence community's process.
