Ex-Trump campaign aide jailed in Russia probe

Papadopoulos was the second person ordered to prison in the sprawling, 16-month Russia collusion investigation of Special Counsel Robert Mueller, and came just over two weeks after two former top aides to Trump were convicted of felony crimes in cases that grew out of the probe.

George Papadopoulos, a one-time foreign policy advisor to US President Donald Trump's election campaign, leaves the US District Court in Washington after his sentencing on September 7, 2018

Trump sought to ridicule the sentence, suggesting that it was trivial accomplishment for an investigation that has cost millions since it began in May 2017 -- while ignoring the 35 indictments, five guilty pleas and one trial conviction Mueller has racked up so far.

Papadopoulos has cooperated for more than a year with Mueller's probe, but it remains unknown whether he has provided the probe with any information supporting allegations of collusion with Russia.

Mueller's office did not immediately comment on the sentence.
