Mark Zuckerberg on Wednesday said Facebook will audit thousands of apps in response to the "breach of trust" created by Cambridge Analytica, the chief executive's first comments since a crisis over data siphoned by the political marketing firm used by the Trump campaign erupted Friday.

In a post on his personal Facebook page, Zuckerberg said it would investigate thousands of apps that used large amounts of data at the time. He said that Facebook will give users new tools for how their data is being used and shared and would further restrict developers' access to data to prevent abuse.
