Some Senators Still Pushing Sanctions Despite Iran Deal

Now want it as a contingency plan, or something

Bipartisan skepticism in the Senate about the newly announced deal with Iran could mean a renewed push for tougher sanctions -- and a veto showdown with President Obama if the administration cannot ease senators' concerns. 

A number of senators, from both sides of aisle, appear to be pushing sanctions as a contingency plan in case the agreement on Iran's nuclear program falters. But some may not be willing to wait -- presenting a problem for the Obama administration, since the deal signed with Iran and five other nations guarantees no new sanctions for six months.
