The FBI on Wednesday expressed “grave concerns” about the public release of a Republican-drafted memo that reportedly contains allegations of FBI partisanship and surveillance abuses, a rare display of public displeasure from the usually taciturn agency.

“With regard to the House Intelligence Committee’s memorandum, the FBI was provided a limited opportunity to review this memo the day before the committee voted to release it,” FBI Director Christopher Wray, a Trump appointee, said in a statement. “As expressed during our initial review, we have grave concerns about material omissions of fact that fundamentally impact the memo’s accuracy.”
