More than two billion users turn to WhatsApp each month to send 100 billion messages and to connect more than one billion calls each day. We are and will continue to be committed to your privacy with end-to-end encryption. Always and forever. Happy 12 years WhatsApp!

My thoughts on the current state of our politics:

[Joe Biden @JoeBiden]

Our nation’s gun violence epidemic is really a cowardice problem — and there’s a lot of politicians in Washington who haven’t shown half the courage @emma4change has. I hope they’re all paying attention. #DemConvention

[Joe Biden @JoeBiden]

I’m doing this for Gabby. I’m doing this for so many families who have lost a loved one to gun violence. We’re going to be on the right side of history. #DemConvention
