Manafort's bail was revoked and he was sent to jail for tampering with two witnesses in connection to his case in Special Counsel Robert Mueller's Russia collusion investigation, according to the media outlet.
US President Donald Trump characterized Manafort's sentence as "tough" and "unfair."
Mueller had previously charged Manafort with conspiracy, money-laundering and acting as an unregistered foreign agent for work he did for the Ukrainian government. Manafort was confined to his home with an electronic bracelet after he was first indicted in October 2017 during Mueller’s investigation into alleged Russian interference in the 2016 presidential election in the US.
