When asked when the inspections might occur, Trump said: "There's no rush. They'll be on the ground at the appropriate time."

The president was also asked about Republicans in Congress, including Sen. Ted Cruz, who have been critical of Trump's interim deal to end the war with Iran.

"I think anybody that's been critical has to be educated — even if they're friends of mine," Trump told reporters.

Critics of the deal, including some Republicans on Capitol Hill, have said the agreement gives Iran significant benefits while getting little immediate in exchange.
