Iran live updates: US-Iran direct meeting not expected Tuesday, Qatari Foreign Ministry spokesperson says

President Donald Trump said on Monday that a U.S. team was heading to Doha, Qatar, amid reports from Iranian state media claiming that there would be no negotiations between U.S. and Iranian teams there.

Trump indicated the team was heading to Doha to discuss Iran's nuclear program during the meeting on Tuesday.

"I think they've already left, or they're just about getting ready to leave. So we'll see how that goes," Trump said while taking questions from reporters in the Oval Office. "But the meeting in Doha is going to be, perhaps important, perhaps not, we're gonna find out."

The president then said the war was "almost won militarily."

"It's really very simple. It's the denuclearization of Iran. We don't want them to have a nuclear weapon and they're not gonna have a nuclear weapon," Trump said.

Secretary of State Marco Rubio and U.S. special envoy to the Middle East Steve Witkoff will brief Congress on Iran during a 4 p.m. ET conference call on Monday, according to multiple sources.

The unclassified phone briefing will be for all House and Senate members, sources said.

This is the first member-wide briefing since President Donald Trump signed the memorandum of understanding between the U.S. and Iran.

Sources said a separate, classified briefing is expected later this week for members on relevant committees.

The House is in session this week with first votes Monday night. The Senate is on a two-week July 4 recess.

White House press secretary Karoline Leavitt said on Fox News on Monday that special envoy Steve Witkoff and Jared Kushner will represent the U.S. at the meeting with Iran in Qatar on Tuesday that President Donald Trump announced, and that these talks are in addition to ongoing technical negotiations.

"I just spoke with the president about it," she said. "Iran has requested a meeting this week. So, special envoy Witkoff and Jared Kushner will be flying to Doha for high-level meetings this week as we continue to discuss the memorandum of understanding. On the sideline of high-level talks will be technical talks."
