After failing to secure a Senate confirmation hearing, U.S. President Donald Trump's most divisive nominee for a Pentagon position so far has taken a different, less-senior policy role at the Defense Department, a spokeswoman said Sunday.

Anthony Tata, a retired Army brigadier general who has called former President Barack Obama a "terrorist leader," will officially perform the duties of the deputy undersecretary of defense for policy, the Pentagon spokeswoman said.

In theory, the position would still offer Tata some degree of influence on hot-button Pentagon policy matters, potentially including Iran.
