Two ex-Trump campaign aides have pleaded not guilty to a series of charges including money laundering and acting as unregistered agents for Ukraine's former government.
Ex-campaign chairman Paul Manafort and his business associate Rick Gates handed themselves in to federal authorities on Monday morning.
Meanwhile a third former member of the Trump campaign...George Papadopoulos...has pleaded guilty to lying to the FBI.
The arrests are the first as a result of special counsel Robert Mueller's investigation into allegations of collusion between the Trump campaign and Russia in the 2016 US presidential election.
