National Security Adviser H.R. McMaster couldn’t say Sunday whether he can work alongside White House chief strategist Steve Bannon.

Over the past few weeks, there have been several negative stories about McMaster, which his allies have attributed to efforts led by Bannon. Bannon and McMaster have an internal disagreement over what to do in the war in Afghanistan. Bannon wants to reduce American military involvement and McMaster wants to deploy more troops, a source familiar with the situation told The Daily Caller.

The national security adviser was asked three times on NBC’s “Meet the Press” whether he can work with Bannon and his answers dodged the questions.
