Got a call this morning from "Jack Rogers" badge 4927 saying the IRS contacted him regarding a tax fraud investigation against me and that I needed to call Steve White at the IRS right away.  Gave the contact number of 202-754-8449 for Steve.  I called the number but it just rang and rang.  Something didn't feel right, so doing some googling and it looks like this is a scam since I have never received anything in the mail.  Have blocked the number now.
