Two Senate Republicans are urging the administration against lifting any sanctions on Iran in absence of real concessions from the regime, following comments from Middle East envoy Steve Witkoff indicating the U.S. had already rolled back some sanctions.

Witkoff, speaking on CNBC on Wednesday, appeared to confirm that President Donald Trump had lifted some oil sanctions on Iran this week, as a signal of cooperation to China and Iran. Trump also said at the NATO summit that Iran would “need money to put that country back into shape. We want to see that happen,” adding, “If they’re going to sell oil, they’re going to sell oil.”

The comments came after Trump posted on Truth Social earlier this week, “China can continue to purchase Oil from Iran” — comments that a senior White House official said did not indicate any policy shift or sanctions relief.

Sen. James Lankford (R-OK) told Jewish Insider he had heard Trump and Witkoff’s comments and that he was not sure what they were referring to, but said no sanctions should be removed until Iran ends its support for terrorism and guarantees that International Atomic Energy Agency inspectors have access to facilities in Iran.

“We’re trying to get additional details, because we’re hearing the sanctions are still there, as well they should be. They still have acts of terrorism. Until we can actually verify that they’ve actually set aside planting terrorism around the region, we need to continue to be able to put pressure on them,” Lankford told JI.

He said the U.S. should not be removing any sanctions at this point, noting, “We can’t verify anything on the ground yet. … They’re literally trying to be able to block out the future [International Atomic Energy Agency] certification,” referring to an Iranian parliament effort to block IAEA inspectors from Iran going forward.

“We know they don’t have the power and the ability to be able to highly enrich uranium at this point, but we don’t have the ability, still, to be able to verify things on the ground,” Lankford continued. “And we have no shift in their policy, as far as we can tell — and certainly not in their charter — on what their stand is for terrorism in the region and to us.”

Sen. John Cornyn (R-TX) said that sanctions relief should “[depend] on what we get for it. If we get complete denuclearization and a peace between Israel and Iran, that might be worth talking about.”

He said that the U.S. should not remove any sanctions preemptively.

“We should get something for it. Certainly, Iran is back on its heels now, and this is exactly the right time to negotiate some sort of long-standing arrangement,” Cornyn said. “I wouldn’t do anything preemptive.”
