A majority of Americans would like Congress to reject the nuclear deal with Iran, a new CNN/ORC poll released on Tuesday found.

The poll found that 52% of Americans believe Congress should reject the deal, while 44% say it should be approved.

The new poll found a sharp partisan gap on whether Congress should approve the deal, with 66% of Republicans and 55% of independents saying Congress ought to reject it and 61% of Democrats saying it should be approved.

Younger adults, who tend to lean more Democratic, are more apt to favor the deal, CNN reported. 53% of those age 18-34 say approve it, while 56% of those age 35 or older say reject it.

There is also an education divide on the deal, with 53% of college graduates saying the deal should be approved, while just 37% of those with a high school degree or less formal education saying they think it should be approved.

The poll was conducted by telephone July 22-25 among a random national sample of 1,017 adults, including 898 registered voters. Results for all adults have a margin of sampling error of plus or minus 3 percentage points.

The poll came as Congress is taking 60 days to review the agreement before approving or rejecting it. President Barack Obama, however, has threatened recently to "veto any legislation" passed by Congress blocking the deal. 

Nancy Pelosi, the Democratic leader in the House of Representatives, last week urged her colleagues to back the nuclear agreement with Iran.

"As you may be aware, I believe that this agreement is a major accomplishment. I am pleased that the response thus far from House Democrats has been so positive," she said in a letter to colleagues, which came as congressional Republicans railed against a UN vote on the deal.

On the flip side, House Speaker John Boehner vowed to "do everything possible" to stop the deal between Iran and nuclear powers from being approved by Congress.

"While the president's Iran deal may have been applauded at the United Nations, I think he faces serious skepticism here at home," Boehner asserted.

"Members of Congress will ask much tougher questions this afternoon when we meet with the president's team, and because a bad deal threatens the security of the American people, we're going to do everything possible to stop it," he added.
