ProPublica reporters are dedicated to investigating government agencies and federal policy. Much of our reporting is fueled by the people who share their experiences, advice and inside knowledge with us.

We are looking for both specific tips and broader expertise. If you’re a current or former government employee, please sign up to be a source for our reporters. We may contact you with questions related to your area of experience.

Your guidance will help us tell important stories. We investigated how a campaign to slash the Internal Revenue Service’s budget hurt the poor and led to gains for tax cheats and big corporations. We laid out the true consequences of relocating the Bureau of Land Management’s headquarters. We found that Chevron was approved to use dangerous plastic-based fuels, even though the Environmental Protection Agency knew they were dangerous. And when we reported on the National Highway Traffic Safety Administration’s failure to enforce safety standards for children’s car seats, it led to impact in Congress and 18 states.

These are some of the agencies and offices that ProPublica reporters are particularly focused on right now. If you work for one of them, we’d appreciate your help.

BLM (Bureau of Land Management)

CDC (Centers for Disease Control and Prevention)

DHS (Department of Homeland Security)

DOD (Department of Defense)

DOE (Department of Energy)

DOI (Department of the Interior)

DOJ (Department of Justice)

DOS (Department of State)

EPA (Environmental Protection Agency)

HUD (Department of Housing and Urban Development)

IRS (Internal Revenue Service)

We take privacy seriously. There is no third-party tracking on this page, but please consider who else may be able to see what you’re doing on your device. We have also set up encrypted tip lines for additional security.

I have a tip to share or want to volunteer my expertise.

Reach Out to Us Using Postal Mail

U.S. postal mail without a return address is one of the most secure ways to communicate. Authorities would need a warrant to intercept and open it in transit.

For better security, you can mail your package or envelope from an unfamiliar sidewalk box instead of your company or agency mailroom. A sidewalk box is also more secure than a post office. You can mail us paper materials or digital files on, for example, a thumb drive.

If you would prefer to send your message to a specific reporter, please address to engagement reporter Maryam Jameel or editor Marilyn Thompson. They will help make sure the right tips go to the right people.
