(Fox News) CENTCOM Commander Gen. James Mattis reportedly is being forced out of his current post several months early, possibly over disagreements with Obama administration officials over policies toward Iran and other international issues.

Journalist Tom Ricks first reported that Mattis was facing an early exit, and insiders tell Fox News that the general was increasingly making the White House nervous while butting heads with National Security Adviser Tom Donilon over Iran.

Mattis has been in charge of military efforts in the Middle East since August 2010, and previously he led the Marines into Iraq in 2003.
