His latest report, however, said that “political plotting and games are not in the best interest of New York State.”

Republicans assailed the district attorney on Friday for not pressing forward with a criminal case now and for his handling of the case.

“The report confirms what I have been saying all along, that former Gov. Eliot Spitzer lied to the people of this state about his direct knowledge and involvement in the Troopergate scandal,” Mr. Bruno said in a statement. “I feel it was a serious mistake not to present this information to a grand jury and proceed with a prosecution,” he added.

A spokeswoman for Mr. Spitzer declined to comment Friday night.

Mr. Soares, who declined to comment, had sought to release a more detailed report but was deterred by grand jury secrecy rules. The district attorney had asked the administration of Gov. David A. Paterson to allow it to release material collected in response to a grand jury subpoena, but Mr. Cuomo’s office, representing the executive branch, released an opinion on Friday saying such a move was not permissible.

The report, which is built largely around Mr. Dopp’s testimony, portrays the former governor as heavily involved in the entire Bruno effort, e-mailing Mr. Dopp frequently after the report was released, keeping close tabs on the progress of the story and analyzing how it played in the press. The governor had his staff arrange for a former top State Police official to talk to The New York Times to keep the story alive, according to the report, in an attempt to show that concerns about Mr. Bruno’s use of the state plane extended back several years.

The latest report is not the end of the matter. The Commission on Public Integrity and the Republican-led Senate Investigations Committee are also conducting inquiries. Mr. Soares’s second investigation started after the integrity commission referred to his office a potential perjury case against Mr. Dopp late last year.

Unlike the last one, Mr. Soares’s new report appeared to vindicate Mr. Cuomo’s findings, which said the administration had tried to discredit Mr. Bruno.
