Analysts at U.S. Central Command were pressured to ease off negative assessments about the Islamic State threat and were even told in an email to “cut it out,” Fox News has learned — as an investigation expands into whether intelligence reports were altered to present a more positive picture.

Fox News is told by a source close to the CENTCOM analysts that the pressure on them included at least two emails saying they needed to “cut it out” and “toe the line.”

Separately, a former Pentagon official told Fox News there apparently was an attempt to destroy the communications. The Pentagon official said the email warnings were “not well received” by the analysts.

Those emails, among others, are now in the possession of the Pentagon inspector general. The IG’s probe is expanding into whether intelligence assessments were changed to give a more positive picture of the anti-ISIS campaign.

The former Pentagon official said there were “multiple assessments” from military intelligence and the CIA regarding the “rapid rise” of ISIS in Iraq and North Africa in the year leading up to the group’s territory grab in 2014.
