But the inspector general, Michael E. Horowitz, found that the F.B.I. cherry-picked and misstated the evidence about Mr. Page. Among the problems was that the law enforcement officials presented his long history of meeting with Russian intelligence officials but did not tell the FISA court that Mr. Page had sometimes told the C.I.A. about those meetings.

One of Mr. Horowitz’s most serious findings was that during the period when the Justice Department was preparing to seek its third renewal of the Page wiretap order in 2017, a lower-level F.B.I. lawyer assigned to assist the Russia investigation team, Kevin Clinesmith, misled a colleague by altering an email from the C.I.A. about its relationship with him.

Mr. Horowitz has referred his findings about Mr. Clinesmith, who has resigned from the F.B.I., to prosecutors. The Justice Department also informed the FISA court about the issue in classified filings in October and November, according to a newly declassified order. But the order, issued Dec. 5 and made public on Friday, indicated that the court wants more action.

Judge Collyer, as the presiding judge on the 11-member court, ordered the department to identify any other FISA applications that Mr. Clinesmith may have worked on. If there are any others, she said, the department or F.B.I. must explain what steps it would take to ensure every fact in them was accurate.

Judge Collyer also asked whether the Justice Department was referring the matter to Mr. Clinesmith’s bar association for potential disciplinary action, like losing his license. (He was not named in the inspector general report or in the newly declassified order, which is partly redacted, but people familiar with the Russia inquiry have identified him.)
