Donald Trump's campaign chairman Paul Manafort has resigned from his position on the campaign
, the Republican presidential nominee said in a statement.
"This morning Paul Manafort offered, and I accepted, his resignation from the campaign," Trump said.
"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."
It's the second high profile departure from the top of Trump's campaign structure after campaign manager Corey Lewandowski left the operation earlier this summer.
