Paul Manafort, the chairman of Donald Trump's presidential bid, has resigned, according to a statement from the campaign.

"This morning Paul Manafort offered, and I accepted, his resignation from the campaign," the statement 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 continued. 
The announcement came two days after Trump reorganized his campaign staff amid falling poll numbers and controversies over the candidate's incendiary comments.
