As the United States reaches an understanding with Iran, criticism is growing inside Donald Trump’s own Republican Party. The party’s hawkish wing worries in recent days that Trump gave up too much in the name of ending the conflict, and CNN reported concern that the agreement could resemble Barack Obama’s 2015 nuclear deal. Senator Lindsey Graham wrote over the weekend that he hoped the new accord would be very different, warned that giving the current regime $300 billion for reconstruction would be like a Marshall Plan for Nazi Germany, and said Trump’s red line on Iran’s nuclear program had been zero enrichment. He added that any deal with Iran must be approved by Congress. Fox News host Mark Levin, former secretary of state Mike Pompeo, former UN ambassador Nikki Haley, conservative commentator Erick Erickson, and additional Republican senators also criticized the outline, with some saying they had not even seen the memorandum of understanding and were especially uneasy about frozen Iranian assets, nuclear provisions, and a reported immediate waiver of oil sanctions.
