WASHINGTON - He may have been the one in the hot seat, but Mark Zuckerberg was ready to hit at Tim Cook if Apple was mentioned during his Senate hearing on Tuesday.
A picture from Zuckerberg's binder reveals the Facebook CEO had notes prepared on how to respond if Cook's comments about the social media site were mentioned.
When Cook was asked what he would do if he was Zuckerberg following the Cambridge Analytica scandal, the Apple CEO replied: 'I wouldn't be in this situation.'
Zuckerberg's notes referenced that there were 'lots of stories about apps misusing Apple data'.
The Facebook CEO also noted that he had 'never seen Apple notify people' about any misuse of customer data.
One bullet point reads: 'Important you hold everyone to same standard'.
Zuckerberg was prepared to compare Facebook and Apple, writing: 'When you install an app on your iPhone you give it access to some information just like when you login with FB.'
Other topics included in Zuckerberg's notes touched on diversity, competition, compensation, accountability, and data safety.
Zuckerberg noted why he would not be firing anyone after the data breach, writing: 'It was about how we designed the platform.'
'That was my responsibility,' he added. 'I'm not going to throw people under the bus.'
The CEO also planned for questions about a resignation, emphasizing that he 'founded Facebook'.
'I made mistakes,' his notes read. 'Big challenge, but we've solved problems before. Going to solve this one. Already taking action.'
Zuckerberg also noted that he uses Facebook 'every day' and so does his family and he invests 'a lot in security'.
He even touched on diversity, writing that 'Silicon Valley has a problem and Facebook is part of the problem'.
'Personally care about making progress, long way to go,' he added.
Zuckerberg got a televised grilling from lawmakers on Tuesday in his first ever appearance before Congress, and immediately took heat for the role his social media site played in the elections.
The CEO tried to reassure lawmakers, saying Facebook would investigate 'every single app that had access to a large amount of information' on the site.
'We believe that we're going to be investigating many apps – tens of thousands of apps,' he told Congress.
'And if we find any suspicious activity we're going to conduct a full audit of those apps to understand how they're using their data and if they're doing anything improper.
Before he could answer a single question, lawmakers went after Facebook for recent security breakdowns.
'There was clearly a breach of consumer trust and a likely improper transfer of consumer data,' said Senate Judiciary Chairman Charles Grassley of Iowa at the start of the hearing.
Grassley said his panel would hold another hearing on the Cambridge Analytica consulting firm and Internet privacy.
'We have made a lot of mistakes in running the company,' Zuckerberg admitted.
'It's pretty much impossible I believe to start a company in your dorm room and then grow it to be at the scale that you're at now without making some mistakes,' he said,
