(Bloomberg) — US-Iranian talks on ending the conflict that has closed the Strait of Hormuz seem unlikely to make major progress soon, a Republican lawmaker said.

“I don’t see any big breakthrough in the near term,” Texas Representative Michael McCaul, a former chairman of the Foreign Affairs and Homeland Security panels, said Saturday on Bloomberg This Weekend. “I think to lower the expectations is smart.”

Prospects for direct talks to end the eight-week war remain slim. Soon after McCaul’s comments, President Donald Trump said he had canceled a trip by his top envoys to Pakistan, which is acting as an intermediary with Iran.

It’s “very hard to trust Iran” even when it signs agreements and “I’m not very sanguine under this regime in Iran that you’re going to have anything in the short term,” McCaul added.

Asked whether Trump’s administration has adequately briefed lawmakers on the war, he said transparency “could be better.”

“They’ve been very close to the vest on this,” said McCaul, who was first elected to Congress in 2005 and isn’t running for reelection this year. “And I understand that, but it’s also important to reach out to Congress.”
