‘Execution mistake’ for delay in flagging US Democrat’s fake video says Facebook CEO

Facebook Inc Chief Executive Mark Zuckerberg on Wednesday said his social media company took too long to flag as false an altered video of US House Speaker Nancy Pelosi that appeared to show the Democratic Representative slurring and tripping through a speech.

Zuckerberg, speaking at a conference in Aspen, Colorado, said the slow response was “an execution mistake on our side.”
