Mr. Trump’s former lawyer Michael D. Cohen negotiated for a Trump Tower project in Moscow many months into the campaign — and later admitted lying about it to Congress, along with tax evasion and other crimes.

Similarly, Mr. Page, a foreign policy adviser, was invited to address a prestigious Moscow institute in July 2016 in what seems to have been a calculated Russian attempt to curry favor. But Mr. Mueller, after a two-year investigation involving roughly 40 F.B.I. agents and other specialists, provided no evidence to support the claim that the adviser had collected a brokerage fee for the sale of a share of the Russian oil giant Rosneft. Nor has any evidence emerged to support the dossier’s claims about D.N.C. moles, Romanian hackers, Russian pensioners — or years of Trump-Putin intelligence trading.

“How many times have hearings on Capitol Hill used information from the dossier?” Mr. Hoffman said. “How much damage has it already caused?”
