Congress probably doesn’t stand with the president so not a good argument….
Check it out:

Yesterday Senate Republicans, led by Lindsey Graham and Bob Corker, tried to force a vote on the Iran Nuclear Negotiations Act of 2014, which would re-impose sanctions on Iran waived during the negotiating process if the P5+1 fail to sign a deal by the November 24 deadline.

Congress wants oversight, said Graham, because Obama “wants a deal too badly.” Now, Graham continued, “is not the time to let President Obama go it alone” with Iran. Wrong, countered Democrat Chris Murphy. “It would send a message that Congress does not stand with the president as the negotiations continue,” said the Connecticut lawmaker.
