"Gates continues to cooperate with respect to several ongoing investigations, and accordingly the parties do not believe it is appropriate to commence the sentencing process at this time", said the joint filing by Mueller and Gates' attorney. Trump tweeted just after 10 AM, after several earlier tweets attacking the Mueller report.
Trump has denied collusion or any other wrongdoing.
He said allegations of collusion between his campaign and Moscow were "nothing more than an excuse by the Democrats for losing an Election that they thought they were going to win".
Gates was the longtime business partner of Trump campaign chairman Paul Manafort, who faces more than seven years in prison for financial and conspiracy crimes after sentencing this week in a separate case in federal court in Washington.
He then turned state's witness against Manafort, testifying that, among other things, they teamed up to hide millions of dollars in offshore bank accounts so Manafort could cheat his taxes.
"Court documents and pre-sentence hearings that dealt with the breach of Manafort's plea deal suggest that prosecutors might have more ammunition to go after the 69-year-old on matters that go directly to the question of a conspiracy with Russian Federation, rather than the financial crimes and violations of foreign-agent laws that he's been charged with to date", The Atlantic's Natasha Bertrand wrote Friday.
Meanwhile, the special counsel's office has confirmed that one of the most prominent members of its team will be leaving his post.
After pleading guilty to tax fraud and failing to register as a foreign agent, US District Court Judge Amy Berman Jackson ruled that Manafort also lied "intentionally" to the FBI, Mueller and the grand jury "concerning matters that were material to the investigation: his interactions and communications" with suspected Russian intelligence agent Konstantin Kilimnik, Bertrand noted.
