Some senators see initial Iran strike assessment, but won't share details

Some senators on Tuesday night viewed the initial classified assessment by U.S. Central Command and the Defense Intelligence Agency on the U.S. strike on Iran's nuclear facilities, multiple aides confirmed.

Members of Senate leadership and the Senate Intelligence Committee viewed the document in a classified setting, the aides said.

Democratic Sen. Mark Warner of Virginia, the vice chair of the Senate Intelligence Committee, viewed the document, as did Sen. Mark Kelly, D-Ariz., who is a member of the committee.

Senators did not give details about what they saw in the classified document.

Senate Majority Leader John Thune said he had "seen some stuff" when asked about the assessment but did not specify what he had seen.

Warner declined to comment to CNN Tuesday night what was detailed in the preliminary report.

"But I've got a lot of questions for the administration," Warner said. "I can tell you there was plenty of debate in the open domain about whether bunker-buster bombs alone could take out Iran's facilities. We also have got questions about where all of Iran's enriched uranium is located at this point and if it's not taken out, what next? Are troops still in harm's way?"

Warner was asked if he believed the briefing might have been postponed due to the preliminary assessment, but he said he did not know.

Earlier Tuesday, a frustrated Minority Leader Chuck Schumer called the Trump administration's postponement of Tuesday's scheduled classified briefing on the Iran-Israel conflict "outrageous," "evasive" and "derelict" -- and former House Speaker Nancy Pelosi called the postponement of the House's briefing "a slap in the face to the Congress of the United States."

"There is a legal obligation for the administration to inform Congress of what is happening. What are they afraid of? Why won't they engage Congress in the critical details, the result of the recent strike, the scope and trajectory of the conflict, the administration's long-term strategy to prevent Iran from obtaining nuclear weapons, the potential risks facing American citizens and our service members who we all have an obligation to protect?" Schumer said while addressing reporters Tuesday afternoon.

Schumer said senators deserve transparency.

"This last-minute postponement of our briefing is outrageous, it's evasive, it's derelict. They are bobbing and weaving and ducking. Senators deserve full transparency," he said.

The Senate's classified briefing, which was set to include briefers from the Department of State as well as Chairman of the Joint Chiefs Dan Caine, CIA Director John Ratcliffe and DNI Tulsi Gabbard, had been postponed to later in the week to allow for other briefers to join.

Schumer suggested, and a GOP leadership aide confirmed, that those other briefers who are expected to join the rescheduled meeting on Thursday are Secretary of State Marco Rubio and Secretary of Defense Pete Hegseth, who are currently at the NATO conference. It's unclear whether the original slate of briefers will still attend Thursday's briefing.

"I was given no explanation for this delay," Schumer told reporters. "They said 'well Hegseth and Rubio will be here Thursday.' We are happy to hear them on Thursday in addition to this briefing, which we think will be far more valuable than hearing from Hegseth and Rubio, who are secretaries and top people and are very good at political talking points. We need facts; we need real information."

Schumer said if Rubio and Hegseth wish to address members he's happy to hear from them. But he also wants to hear from the original slate of briefers.

"If they want to come up on Thursday in addition -- not in replacement of this hearing -- that is OK," Schumer said. "But the obstruction of this administration on a crucial issue like this where American lives and particularly the lives of American service members are at stake, is their obligation and it undermines the very principles of accountability and oversight that safeguard our democracy."

The delay came as an early intelligence assessment showed the attack did not completely destroy Iran's nuclear program and likely set it back only by months, according to two people familiar with the assessment.

While the White House is disputing the assessment, House Minority Leader Hakeem Jeffries said that it’s further justification for a congressional briefing.

“It's one of the reasons why we need both a Gang of Eight briefing immediately and a classified briefing for all members of the House of Representatives,” Jeffries said.

Asked on CNN if he believed the briefing might have been postponed because of the preliminary assessment, Warner said he did not know.

Schumer said he has still not received a more formal briefing from the administration since he received a brief call informing him of Saturday night's strike just before it occurred. That call, he said, lacked any specific details.

The House's classified briefing set for Tuesday afternoon was postponed as well, which prompted a legislative tantrum on the floor Tuesday afternoon, with lawmakers demanding an explanation.

Democratic Rep. Yvette Clarke, the chair of the Congressional Black Caucus, attempted four times to seek an explanation from the chair as part of a "parliamentary inquiry."

Clarke's inquisition was dismissed repeatedly by the presiding chair, Republican Rep. Scott DesJarlais, who informed Clarke that she had not properly stated a parliamentary inquiry.

After some back and forth, Clarke then informed DesJarlais that without an explanation for the postponed briefing, she'd offer a motion to adjourn. That forced the lawmakers to return to the chamber for an unexpected vote to defeat the Democratic motion.

Pelosi criticized the postponement of the briefing.

"We must all exercise our best judgement in how we prevent Iran from having a nuclear weapon and honor our relationship with Israel in the interest of our national security. But the unjustified cancellation of this briefing by the Trump administration is an intolerable insult to their co-equal branch of government and the constitutional requirement that the president comes to Congress before going to war," the California Democrat said. "The president owes the American people an explanation on why his administration is keeping them and their representatives in the dark."

It's not yet clear when the House's briefing will be rescheduled.

When the meetings occur, it's expected that lawmakers, especially Democrats, will be looking for answers and evidence at the briefings from the administration -- specifically why Trump said there was an imminent threat and carried out U.S. strikes on Iran's nuclear sites over the weekend.

Their meetings come after several lawmakers on Capitol Hill argued the military action was unconstitutional. There are several bipartisan resolutions that could receive a vote in coming days that may put some lawmakers in uncomfortable positions as they consider whether Trump ignored the role of Congress in striking Tehran.

Republican Rep. Thomas Massie and Democratic Rep. Ro Khanna introduced a War Powers Resolution last week to rebuke the president's decision to launch strikes. As Massie continued to rail against Trump and his role in the conflict, the president lashed out at the Kentucky Republican, saying he was "not MAGA" and threatened to campaign for Massie's Republican primary opponent in the next election.

Massie has now softened his approach, telling reporters at the Capitol on Monday that he's now considering pulling the bipartisan War Powers Resolution.

"If the ceasefire holds, and we're not engaged in hostilities, then it's a moot point. I wouldn't need to bring it to the floor," Massie said.

Massie also added that he is open to patching things up with the president: "I'd like a ceasefire between me and President Trump. If I can get the same deal, after his bunker busters he dropped on me."

Trump on Monday announced that Israel and Iran had agreed to a ceasefire, after more than a week of fighting following Israel's strikes -- and subsequent U.S. attacks -- on Iran's nuclear program. Hours after the ceasefire took effect, Israel said Iran violated it -- which Iran denies.

Trump expressed anger at both Israel and Iran, accusing both of violating the ceasefire agreement shortly after it began.

"I'm not happy with Israel. OK, when I say now you have 12 hours, you don't go out in the first hour and just drop everything you have on them. So I'm not happy with them. I'm not happy with Iran either," Trump said to reporters Tuesday morning.

Speaker Mike Johnson said late Monday that he expects the House briefing to have a different "tone" in the light of the ceasefire.
