A recently leaked assessment from the Defense Intelligence Agency (DIA) concluded that last weekend's airstrikes may have only set Iran's nuclear program back by a few months.

The White House has responded to the leak by limiting Congress' access to classified information, a decision which has infuriated Democrats. 

FBI is investigating leak of documents

The Washington Examiner reported on Wednesday that a White House spokesperson confirmed the new policy and pointed to remarks made by press secretary Karoline Leavitt.

"I am told by the FBI that the leak already is being investigated, and it absolutely should be," Leavitt said during an interview with Fox News.

"Because this was a top secret intelligence analysis that very few people in the United States government had access to see," she added.

Democrats upset over rescheduling of planned briefing

The newspaper also noted that Capitol Hill Democrats were left frustrated after the president cancelled two all-member briefings which had been scheduled for Tuesday.

The briefings were expected to focus on circumstances in the Middle East and would have featured appearances by Director of National Intelligence Tulsi Gabbard, CIA Director John Ratcliffe, and Joint Chiefs Chairman Dan Caine.

However, the events were rescheduled for Thursday in order to accommodate Defense Secretary Pete Hegseth and Secretary of State Marco Rubio, both of whom attended a North Atlantic Treaty Organization in Europe.

Sen. Chuck Schumer angry over not receiving more details of Iran strike

That excuse did not sit well with Senate Minority Leader Chuck Schumer, who slammed the last minute rescheduling as "outrageous."

"We don't care," the Examiner quoted Schumer as saying. "I think Hegseth is just going to give us talking points. But Caine is scheduled to come. He probably knows more about the military operations both now and in the future than anybody."

What's more, Schumer complained about not getting a heads-up from the White House prior to U.S. plans striking targets in Iran.

"Shortly before the action occurred, or during it, we’re not sure which, they called me up and said, 'We're taking imminent action. Can’t tell you what country.' I said, 'Can you give me some details?' They said, 'No,'" he fumed.
