Gates continues to cooperate

WASHINGTON -- Rick Gates, a former Trump campaign aide and key cooperator in the special counsel's Russia probe, is not ready to be sentenced because he continues to help with "several ongoing investigations," prosecutors said in a court filing Friday.

Gates is a central figure in special counsel Robert Mueller's investigation of Russian election interference and possible coordination with the Trump campaign. But he is also helping federal authorities in New York who are looking into Trump's inaugural committee as well as lobbying on behalf of foreign interests by prominent Washington insiders.

The joint filing by Mueller's office and Gates' attorneys comes amid signs the Russia investigation is winding down. But it's unclear whether Friday's delay is an indication Mueller may submit his confidential report soon or whether it's related to the status of the other investigations.

The filing asked for another 60 days to update U.S. District Judge Amy Berman Jackson on whether Gates can proceed to sentencing. The judge granted the request later Friday.

Gates pleaded guilty last year to conspiracy and false statement charges related to Ukrainian lobbying and political consulting he carried out with former Trump campaign chairman Paul Manafort, who has been sentenced to more than seven years in prison.

Gates helped the government in obtaining a trial conviction of Manafort last year. Prosecutors have noted he continues to provide information about Manafort's time on the Trump campaign, though neither man has been charged with any crimes related to Russian election interference.
