Ex-Trump aide Manafort to cooperate in Russia probe

President Donald Trump's former campaign chairman Paul Manafort agreed Friday to cooperate in the Russia collusion investigation in a plea deal that left the White House looking increasingly under siege by Special Counsel Robert Mueller. Manafort, who led Trump's election operation at the height of the campaign in the middle of 2016, admitted reduced charges of conspiracy just days before he was to go on trial for money laundering, illegal lobbying and witness tampering. The surprise deal brought to seven the number of people who have pleaded guilty in cases tied to Mueller's 16 month old investigation into whether the Trump campaign colluded with Russia.
