If the US administration wants to seek special procedure to quicken Congressional consideration of the accord, it should show how the NSG decision is consistent with the Hyde Act, including which technology can be sent to India and what impact a nuclear test by New Delhi would have, he said.

"Before we vote, Congress needs to study the NSG decision, along with any agreements that were made behind the scenes to bring it about," he said echoing his earlier comments that Congress should not rush through the deal until the Administration proved that it did not cut any ‘side deals’ at the NSG to get the waiver for India.

"The burden of proof is on the Bush Administration so that Congress can be assured that what we're being asked to approve conforms with US law," he added.

The Californian Democrat who raised a political storm in India by releasing on the eve of NSG meeting responses by the State Department to questions posed by his predecessor Tom Lantos, said he supports civil nuclear cooperation with India.

"I support cooperation on civilian nuclear energy with India. I oppose policies that would lead to a nuclear arms race or undermine proliferation standards," Berman, Chairman of the powerful House Foreign Affairs Committee, said in a statement issued from Van Nuys, California.
