An election campaign adviser to Donald Trump has pleaded guilty to lying to the FBI about the timing of meetings with alleged go‑betweens for Russia.
George Papadopoulos admitted the talks happened while he worked for Trump.
He said he had been told the Russians possessed "dirt" on Hillary Clinton.
Separately, former Trump campaign manager Paul Manafort pleaded not guilty to charges of money laundering unrelated to the 2016 election.
The charges against Papadopoulos are the first to be brought the special counsel investigating alleged links between Russia and the Trump campaign.
