The U.S. State Department has confirmed receipt of a letter from Congressman Dana Rohrabacher addressed to Secretary of State Hillary Clinton.

He proposed in the letter to support the idea of annexing Iranian Azerbaijan (northwest portion of Iran) to Azerbaijan, State Department spokesman said.

As Victoria Nuland noted at a briefing, though Secretary of State replied to the letter, the details won’t be publicized.

"We support the principle of territorial integrity," Nuland said, asked if the U.S. backs fragmentation of states, Trend reported.
