From another post. How to report election irregularities:


Election Fraud Hotline # 800-895-4152
Just want to make sure people can find this number to the Trump team's election fraud war room if they have real evidence (first hand, credible, and in a state where it really makes a difference right now). If you saw something SAY SOMETHING. If something happened to you, say something. Report it to your local election authority, yes, tell the DOJ/FBI (see below), but report it too to the lawyers who can do something about all this at this point.

Now is the time. We can all do our part and what we know as a collective can make a difference.

Election-crime complaints should be directed to the local U.S. Attorney’s Offices or the local FBI office. A list of U.S. Attorney’s Offices and their telephone numbers can be found at [link to www.justice.gov] A list of FBI offices and accompanying telephone numbers can be found at www.fbi.gov/contact-us.
