The director of national intelligence intensified attacks on assessments about Russia’s role in the 2016 presidential election.

The Justice Department announced on Wednesday the formation of a task force to look into unsubstantiated allegations by President Trump that President Barack Obama and his aides ordered an investigation into the 2016 Trump campaign’s connections to Russia to destroy Mr. Trump.

The announcement, which came in an ambiguous, bare-bones statement on the department’s website, was a continuation of Mr. Trump’s campaign of retribution. It also represented yet another Trump pivot away from the political morass of the Jeffrey Epstein files in targeting Mr. Obama, whose presidency set off a wave of reactionary anger that helped propel Mr. Trump from a punchline to political dominance.

The move came hours after Tulsi Gabbard, the director of national intelligence, ramped up her attacks on Mr. Obama, releasing a document that she said undermined the conclusion of his intelligence agencies that Russia favored the election of Mr. Trump in 2016.

Ms. Gabbard said that after Mr. Trump’s first election, Mr. Obama ordered an intelligence analysis that was subject to “unusual directives” from him. She criticized that assessment as using unclear or unknown sources.

Under questions from reporters, she said Obama administration officials had led to a “yearslong coup and treasonous conspiracy” against Mr. Trump.

Asked if she thought Mr. Obama was implicated in criminal behavior, Ms. Gabbard said she had referred documents to the F.B.I.
