Business mogul Donald Trump's acceptance speech for the Republican presidential nomination Thursday night won praise from David Duke, the former head of the Ku Klux Klan.

Just 10 minutes after Trump finished his lengthy address at the Republican National Convention in Cleveland, Duke took to social media, tweeting several comments including "couldn't have said it better!"

"America is far less safe – and the world is far less stable – than when Obama made the decision to put Hillary Clinton in charge of America's foreign policy," Trump said Thursday.

"I am certain it is a decision he truly regrets," he said. "Her bad instincts and her bad judgment – something pointed out by Bernie Sanders – are what caused many of the disasters unfolding today."
