If it’s on the radio, it must be true. /s
But seriously, this sounds like an echo of the controversy that erupted a few months ago when it was discovered that a Cruz PAC and Fiorina’s campaign had the same address in Virginia.
In fact, both were using a Virginia based campaign accounting firm “Election CFO”, and used their address for fundraising and for FEC filings.
This might be the basis of what you heard.
For the record, the address shown on Nehlen’s website for donations is Kenosha, WI.
I trust the authority of the man who said it. He’s a careful researcher. It’s easy to get a Kenosha address.
