The complaints, lodged by analysts at U.S. Central Command in 2015, are separate from allegations that analysts made to the Defense Department inspector general, who is now investigating "whether there was any falsification, distortion, delay, suppression, or improper modification of intelligence information" by the senior officials that run CENTCOM's intelligence group.
This second set of accusations, which have not been previously reported, were made to the Office of the Director of National Intelligence (ODNI). They show that the officials charged with overseeing all U.S. intelligence activities were aware, through their own channels, of potential problems with the integrity of information on ISIS, some of which made its way to President Obama.
The analysts have said that they believe their reports were altered for political reasons, namely to adhere to Obama administration officials' public statements that the U.S.-led campaign against ISIS is making progress and has put a dent in the group's financing and operations.
