GOP nominee Mitt Romney said Saturday that the deaths of four American diplomats in Libya was a “tragic reminder” that the world needed “strong leadership” from Washington and focused on the Obama administration’s relations with China to accuse the president of falling short on that score.

“The attacks on our diplomatic outposts are, of course, a tragic reminder that the world remains a dangerous place, and that America’s leadership is needed,” said the GOP nominee in his weekly podcast. “And for America to be able to provide strong leadership in the world, we have to have a strong economy here at home.”
