If you see something, leak something. Telling the world holds people in office accountable, no matter how big or small it may be.

There are a number of ways to contact me securely, in ranking order.

Encrypted calls and texts

I use both Signal and WhatsApp for end-to-end encrypted calling and messaging. The apps are available for iPhones and Android devices.

You can reach me at on Signal or WhatsApp.

I will get back to you as soon as possible if I don’t immediately respond.

Encrypted instant messaging

You can also contact me using “Off The Record” messaging, which allows you to talk to me in real time on your computer. It’s easy to use once you get started. This helpful guide will show you how to get set up.

You will need a Jabber instant messaging account. There are many options to choose from. For anonymity, you should create an account through the Tor browser.

You can reach me at: during working hours.

Send me PGP email

PGP, or “Pretty Good Privacy,” is a great (but tricky-to-use) way of emailing someone encrypted files or messages. PGP works on almost every email account and computer, but using it on your work or home email address won’t hide who you are, or the fact that you sent a reporter an email.

The EFF has a set of easy-to-use tutorials on how to get started.

You will need my public PGP key to email me securely, available here.

You can also verify my PGP fingerprint to be sure it’s me: .

Send me snail mail

Sometimes, sending a USB stick or documents is easiest if you mail them along. If you are to do so, make sure you send them from outside your ZIP code as mail is often scanned and printed with the location it was dropped off — even if you don’t leave a return address.

You can send me snail mail at the following address:

Don’t leave your return address. But if you want me to contact you again, leave a single word or phrase on the inside of the envelope and message me with that phrase over Signal. That will help me identify you as the sender.
