I received a call from Kevin Mason at this number as well -- SCAM SCAM SCAM mention the US Treasury, Federal offense, etc.
Think they might be trying to scam money out of senior citizens.
Boy, this guy is on a roll this morning. I received this at 9:36am on my biz line. Another fake IRS scam. Never answer a call that says Washington, DC, it's always a spoofed number.
