The executive chairman of a website linked to the UK Independence Party has been charged with masterminding Donald Trump's election campaign.
Stephen Bannon joins the campaign as chief executive in a shakeup which comes as new polls put Mr. Trump way behind Democratic rival Hillary Clinton in key battleground states.
Mr. Bannon is executive chairman of conservative website Breitbart News, which is known for its conservative political commentary. Breitbart's UK editor-in-chief, Raheem Kassam, was appointed as a senior adviser to Nigel Farage in the run-up to the 2015 general election, and Mr. Farage has written several opinion pieces for the site.
Following Britain's vote to leave the European Union, Mr. Bannon, who also hosts a US satellite radio show, congratulated Mr. Farage during an interview and the then-Ukip leader expressed a "massive thanks to Breitbart, on both sides of the pond."
On Tuesday Mr. Trump gave a speech in Wisconsin which extensively referenced the recent riots in the state's largest city, Wisconsin.
Mr. Trump said "law and order must be restored," and suggested Ms. Clinton had helped stoke a "dangerous anti-police atmosphere."
The Republican candidate said: "Those peddling the narrative of cops as a racist force in our society – a narrative supported with a nod by my opponent – share directly in the responsibility for the unrest in Milwaukee, and many other places within our country.
"The war on our police must end. It must end now."
