US Democratic senator calls lack of briefings on US-Iran talks 'dangerous'

"As far as I know the administration has provided zero briefing to this committee on the negotiations, so they seem to be happening totally in secret," US Senator Chris Murphy told Iran International.

The Connecticut Democrat sits on the Senate Foreign Relations Committee.

"I think that's pretty dangerous for the American people to be kept in the dark about these negotiations, especially really sensitive negotiations that involve a potential nuclear war," he added.
