Donald Trump’s top aide has denied reports of deepening divides within the campaign after a series of verbal battle royales with Khizr Khan caused by the Republican nominee.

“The campaign is in very good shape. We are organized. We are moving forward,” Paul Manafort told Fox News. US media outlets reported the campaign was in turmoil after Trump repeatedly attacked the parents of the fallen US solider.

Staffers apparently told CNN that they “feel like they are wasting their time”.

However, Mr. Manafort blamed those reports on Mr Trump’s opponent Democrat Hillary Clinton.

“This is another Clinton narrative that she put out there and the media is picking up on,” he said. “Mr Trump has appeared this week at crowds that are overflowing into the street.”
