Very likely a smear campaign, as posted by many anons previously.
Not sure if posted previously, but had a short look into it, and it seems this all goes back to a law suit filed by an employee of Alpha Omega Winery LLC (Analene Anase) back in 2016.
Attached is the PDF filed back then.
It is said that 25 men boarded the yacht, who had bid on & won a cruise on the yacht at a charity fundraiser.
(Did Nunes even attend that fundraiser?)
Nunes was invested in Alpha Omega w/ an amount b/w $50,000 – $100,000 as a "limited partner". Limited partners had little to do w/ the companies activities it is reported.
Don't think this is gonna go anywhere, and at this point I don't believe Nunes was among the 25 on that yacht that night.
