Facebook said Wednesday that a data scandal that has rocked the company affected more people than we thought. 

Data from 87 million people was improperly shared with Cambridge Analytica, a digital consultancy with ties to the Trump presidential campaign -- higher than the 50 million accounts previously reported. For context, that's more than the entire population of Germany, which has a population of 82 million.
