House intelligence chairman Devin Nunes is asking for additional intelligence assessments related to the nuclear agreement with Iran.

In a letter Tuesday to Director of National Intelligence James Clapper, Nunes asked for an analysis of competing hypotheses about whether intelligence agencies will be able to verify Iran's compliance with the deal.

The California Republican is also seeking an analysis of Iran's nuclear intent, and what he called an "out of the box" assessment of a full range of issues relating to Iran and the nuclear agreement.

He wants the documents by Sept. 3. Intelligence agencies generally comply with requests from their oversight chairmen.

Nunes and most Republicans oppose the nuclear agreement the Obama administration negotiated with Iran.
