Representative Matt Gaetz, Republican of Florida and one of the president’s most ardent supporters on Capitol Hill, praised Mr. Trump’s decision in a statement and said it came in the face of “unnecessary delays, redactions and refusals.”
“These documents will reveal to the American people some of the systemic corruption and bias that took place at the highest levels of the D.O.J. and F.B.I., including using the tools of our intelligence community for partisan political ends,” Mr. Gaetz said.
Representative Adam B. Schiff of California, the highest-ranking Democrat on the House Intelligence Committee, accused the president of abusing his power “to intervene in a pending law enforcement investigation by ordering the selective release of materials he believes are helpful to his defense team and thinks will advance a false narrative.”
In addition to parts of the application, Mr. Trump also ordered the director of national intelligence and law enforcement officials to declassify F.B.I. interviews about the case with Bruce G. Ohr, a Justice Department official who has been caught up in Mr. Trump’s attacks on national security officials.
Mr. Ohr, a veteran prosecutor who fought Russian organized crime for years, met repeatedly with a British spy who specialized in Russia, Christopher Steele, who compiled a dossier of explosive, unverified claims about Mr. Trump during the 2016 campaign. Mr. Steele was also an F.B.I. informant, but agents ended that relationship in late 2016 because he had spoken to journalists about the work he did for the bureau.
Mr. Steele investigated ties between Mr. Trump and Russia for the same research firm, Fusion GPS, where Mr. Ohr’s wife was a contractor.
Mr. Ohr met with Mr. Steele almost a dozen times from late 2016 to May 2017, according to congressional officials. F.B.I. agents interviewed Mr. Ohr after the meetings and documented the information.
Mr. Ohr was the only current official singled out by Mr. Trump when he announced this summer that he was reviewing the clearances of several national security officials. Mr. Trump has also repeatedly attacked Mr. Ohr, calling for him on Twitter to be fired.
