The person who sent prominent Democrats explosive devices in the mail could spend the rest of their life in prison.

Federal law states that anyone who “transports or receives, or attempts to transport or receive, in interstate or foreign commerce any explosive with the knowledge or intent that it will be used to kill, injure, or intimidate any individual or unlawfully to damage or destroy any building, vehicle, or other real or personal property” can be sentenced to up to 10 years in prison.
