The Wall Street Journal reports that President Barack Obama wrote a secret letter to Iranian Supreme Leader Ayatollah Ali Khamenei about working with Iran to fight ISIS.

The letter also reportedly addressed Iran’s nuclear program and stressed that cooperation on ISIS was contingent on a nuclear deal.

White House Press Secretary Josh Earnest said he’s not in a position to discuss private correspondence.

Tonight on “Hannity,” Lt. Col. Ralph Peters said Obama is much more comfortable in secret relations with Iranians than in being honest with Americans.

Peters said the letter will be read as a betrayal by Middle East allies and that it plays into the hands of ISIS.

“Why do Iran’s dirty work for them? Iran owns the Baghdad government that Obama keeps praising and saying he’s going to rely on. It owns them. Why are we helping Shias kill Sunni? Use common sense, dammit. If you want to fight Sunni terrorists, a vast movement of Sunnis, you need Sunni allies.”
