After weeks of making clear that GOP leaders in Congress would try to block a nuclear deal with Iran by voting on a measure to 'disapprove' of the agreement, a group of House Republicans forced a last minute change of plans that ultimately may send a mixed GOP message to voters about the Iran agreement.

The Senate will still try to vote to 'disapprove' of the deal, but Democrats are increasingly confident they can filibuster that resolution - which now won't even be voted on in the House.

Instead, the House will take three different votes this week:

+ One plan will declare that President Obama has not turned over all "side agreements" on the Iran nuclear deal, as the GOP will argue that the Iran deal is not yet in effect.

+ A second vote will be a straight up-or-down vote on approving the Iran deal (instead of 'disapproval').

+ The third measure would prohibit the President from moving to lift any sanctions against Iran.

The House will vote on the first bill on Thursday, and save votes on the other two measures for Friday.

The Senate seems likely to take a cloture vote on Thursday, likely wrapping up the debate in that chamber first.
