Paul Manafort, campaign chairman of Donald Trump, the US GOP presidential nominee, has resigned his position, the campaign confirmed on Friday.
Manafort’s resignation comes as his ties to pro-Russian forces in Ukraine were revealed.
Earlier this week, Trump brought in Stephen K. Bannon, chairman of the Breitbart News website, as his campaign’s chief executive, pushing aside Manafort.
Manafort had drawn public scrutiny after reports linking him to former Ukrainian Leader Viktor Yanukovych.
According to reports, Manafort, 67, joined the campaign in March, and had clashed with campaign manager Corey Lewandowski, who was fired three months later.
“This morning Paul Manafort offered, and I accepted, his resignation from the campaign,” Trump said in a statement.
“I am very appreciative for his great work in helping to get us where we are today, and in particular his work guiding us through the delegate and convention process.
“Paul is a true professional and I wish him the greatest success.”
The shakeup comes less than three months to the election in November.
