President Trump demanded details from the F.B.I. about the agents’ interview of James B. Comey, the former director, according to a court filing unsealed on Tuesday. The demand suggests the intense personal involvement of Mr. Trump in investigating one of his longtime critics.

The filing, from the Justice Department, was in response to a lawsuit by the group American Oversight, which had sought records related to Mr. Comey’s termination. The department revealed that on April 11, 2018, Mr. Trump had asked about the interview, which took place on July 7, 2017. This interview was reportedly the basis for Mr. Trump’s decision to fire Mr. Comey.

Mr. Comey was fired in May 2017, amid an ongoing investigation into Russian interference in the 2016 election. The F.B.I. had been investigating Mr. Trump’s campaign. The court filing does not specify what details Mr. Trump sought, nor does it say whether the F.B.I. provided them. The F.B.I. has previously stated that Mr. Comey was fired due to his handling of the investigation into Hillary Clinton’s emails, not because of the Russia investigation.

This revelation adds another layer to the ongoing scrutiny of Mr. Trump’s actions during his presidency and his interactions with the F.B.I. The court filing was made public as part of the ongoing legal proceedings related to the F.B.I. records.
