The FBI said Wednesday it has “grave concerns” about the classified memo put together by Republicans on the House Intelligence Committee, and said it includes "material omissions of fact."

“The FBI was provided a limited opportunity to review this memo the day before the committee voted to release it,” the agency said Wednesday. “As expressed during our initial review, we have grave concerns about material omissions of fact that fundamentally impact the memo’s accuracy.”

According to a prior report, FBI Director Christopher Wray warned the White House to object to the release of the memo, spearheaded by the staff of House Intel Chairman Devin Nunes, R-Calif.

Wray reviewed the memo on Capitol Hill on Sunday, and the committee voted along party lines Monday night to make the four-page memo public. The vote gave President Trump five days to object to making the memo public, after which the committee can release it.

In response, Nunes said top officials at the Justice Department and FBI “used unverified information in a court document to fuel a counter-intelligence investigation during an American political campaign.”

“Once the truth gets out, we can begin taking steps to ensure our intelligence agencies and courts are never misused like this again," he said.

Trump was caught on a hot mic Tuesday night tell Rep. Jeff Duncan he would “100 percent” release the memo. The White House received the memo late Monday, and has said there is now a multi-agency review going on.

Trump’s chief of staff John Kelly said during a radio interview early Wednesday that he thinks the memo “will be released here pretty quick.”

Democrats on the panel have prepared their own memo that they say fills in the blanks and counters the “misleading” GOP memo, but the panel voted Monday to keep that one private for House members only, until it follows the same steps for release that the Nunes memo took.

In a Washington Post op-ed published Wednesday afternoon, House Intel ranking member Adam Schiff, D-Calif., said the memo “crosses the line.”

Schiff said the memo “cherry-picks facts, ignores others and smears the FBI and the Justice Department,” and also alleged that Nunes has not read the classified documents that the memo characterizes.

Schiff charged that the release of the memo is to undermine special counsel Robert Mueller — who was appointed in May by Deputy Attorney General Rod Rosenstein to investigate Russian influence in the 2016 presidential election and possible collusion with the Trump campaign.

The GOP memo reportedly details abuses of the federal surveillance court process under the Foreign Intelligence Surveillance Act by top officials at the FBI and Department of Justice, possibly against associates involved in the Trump campaign.

"The FBI takes seriously its obligations to the FISA Court and its compliance with procedures overseen by career professionals in the Department of Justice and the FBI. We are committed to working with the appropriate oversight entities to ensure the continuing integrity of the FISA process," the FBI said Wednesday.

Rosenstein, former FBI Director James Comey, and outgoing FBI Deputy Director Andrew McCabe are reportedly named in the memo as well.

McCabe stepped down from his position on Monday ahead of the release of an inspector general’s report on the FBI’s handling of its probe into Hillary Clinton’s private email server. McCabe had also drawn ire from Trump and GOP lawmakers for biased.

The Washington Post reported late Tuesday that Rosenstein made a last-minute plea to White House chief of staff John Kelly about the “dangers” of releasing the memo. He was reportedly joined by Wray in that Monday meeting.

Last week, Assistant Attorney General Stephen Boyd told Nunes in a letter that releasing the memo would be “extraordinarily reckless.”

In a statement, Senate Judiciary Committee ranking member Sen. Dianne Feinstein said the FBI’s statement “is the latest reason not to release it.”

Editor's note: An earlier version of this story stated incorrectly that the current FBI director, Christopher Wray, was allegedly listed in the memo instead of the previous director, James Comey. The Washington Examiner regrets the error.
