Received a call from this number showing that it was from DC, USA. I suspected it was a scam caller, so I didn't pick up. They left me a lousy unclear voicemail that said "Appearance before the magistrate judge or grand jury for a federal criminal lawsuit. My number is (202) 558-2078. I repeat, (202) 558-2078. By you cooperate with us and help us to help you. Thank you. Goodbye." I blocked this number on my phone afterwards. A few hours later, I received another stupid call from them, but with a different phone number.
