MSNBC presenter Alex Witt was speaking to Cornell William Brooks, the president of the National Association for the Advancement of Colored People (NAACP), about allegations of racism against Republican nominee Donald Trump’s campaign. Both Mr Trump and Democratic nominee Hillary Clinton have raised the issue of race in speeches – with Mr Trump recently branding his rival a “bigot”. Witt was prepping to show Mr Brooks a clip from one of Mrs Clinton's speeches when the advert for the fast food chain was accidentally aired. She said: “As you know, Hillary Clinton says that Trump’s campaigning is appealing to a fringe in the Republican Party that is racist.

“I want to listen to part of her speech with you and get your reaction. So here it is.” But instead of seeing the former First Lady, a clip showing an actor playing famous KFC founder Colonel Sanders was played. A clearly embarrassed Witt quickly moved on from the error, telling Mr Brooks and her viewers the advert was “absolutely not what we were going to play”. In the most bitter US presidential election campaign in recent memory, the two candidates have accused each other of discriminatory comments and policies. Speaking at a campaign rally in New Hampshire, Mr Trump said: “It’s the oldest play in the Democratic playbook. When Democratic policies fail, they are left with only this one tired argument. “You’re racist, you’re a racist. It’s a tired, disgusting argument.”

Mr Trump continued: “People who want their laws enforced and respected, and who want their border secured, are not racists. They are patriotic Americans of all backgrounds who want their jobs protected and their country kept safe.” “People who speak out against radical Islam, and who warn about refugees, are not Islamophobes. "They are decent American citizens who want to uphold our values as a tolerant society, and who want to keep the terrorists out of our country.” The real estate billionaire has also accused Mrs Clinton of being someone who “sees people of colour only as votes not as human beings worthy of a better future”.
