Donald Trump's campaign chairman Paul Manafort resigned on Friday in the wake of campaign shake-up and revelations about his work in Ukraine.
In a statement issued as he arrived in Louisiana to tour the flood-ravaged state, Trump said Manafort offered his resignation Friday morning. The billionaire called Manafort "a true professional."
"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," Trump said.
Manafort's resignation comes a day after The Associated Press reported that confidential emails from Manafort's firm contradicted his claims that he had never lobbied on behalf of Ukrainian political figures in the U.S.
Trump's son, Eric Trump, told Fox News in an interview that will air Sunday that his father worried questions about Manafort's past were taking attention away from the billionaire's presidential bid.
