Tennessee Republican Sen. Bob Corker and Senate Majority Leader Mitch McConnell reportedly may have plan Bs in Congress for the Iran nuclear deal, Newsmax websited reported on Friday, August 28th.

Congress has the authority to review the agreement, and if its review leads to legislation aimed at killing the agreement, President Barack Obama would veto it. Corker, chairman of the Senate Foreign Relations Committee, has said in the past he anticipated enough opposition to override that veto, the Tennessean reports.

But the Fiscal Times reports both Corker and McConnell have alternate plans.

According to the Fiscal Times, one measure would be a “poison pill” approach, in which McConnell would open the resolution to a series of politically flammable amendments that would put wavering Democrats on the spot, and enable the Republicans to score political points, even if they don’t prevail.

Some amendments were offered in April by Sens. Marco Rubio (R-FL), Tom Cotton (R-ARK) and other conservatives, and include making adoption of the nuclear deal contingent on Iran recognizing the state of Israel, and the release of three American hostages.

Corker suggested another approach in his speech to the local chamber of commerce, the Tennessean reports.

“I think what Congress will do is come back around with some very, very strong provisions relative to Iran, but also probably some very strong provisions relative to some regional … strategy that is very supportive of allies that we have in the region,” Corker said.

Fiscal Times reports Corker favors the Senate developing legislative provisions that would keep the economic pressure on Iran and come down hard if Iranian leaders later violate the terms of the agreement – with the goal of keeping Iran in line with the threat of renewed economic sanctions.
