Jeremy Peter Green says he bought clintonkaine.com for $7.30 in 2011 and recently sold the domain to the Trump campaign for $15,000, which is now using the site to troll Hillary Clinton and her running mate, Tim Kaine.

At the bottom of the website clintonkaine.com, which is filled with negative headlines about the Democratic ticket, is a note: "Paid for by Donald J. Trump for President, Inc." A Politico reporter noted the apparent Trump takeover of the domain Monday morning.

“CLINTON: SANDERS SUPPORTERS LIVE IN PARENTS BASEMENT” reads the top story, with a link to a Politico item.

As of Monday morning, all of the other links on the page went back to reports posted on the Republican National Committee’s research page.

Ironically, Green, a 28-year-old attorney, says he is actually a Clinton supporter who plans to volunteer for her on election day as a legal poll observer.

So how does he feel about the fact that the domain he once used is now attacking the candidate he supports?

"I am indeed okay with it. By the time Trump got his hands on the domain, it was getting only 50 visitors a day. Definitely not a $15,000 domain! I'm very happy to have Trump's money," Green told USA TODAY in an email.

"I bought it because I knew that if Clinton-Kaine ended up being the 2016 ticket, I would be able to use the web traffic have some fun with domain, and eventually sell it. I sold the domain because I wanted money," Green said. He had originally offered the domain to the Clinton campaign for $15,000 but said he as willing to go as low as $10,000 — they wouldn't bite.

"Clinton's campaign said they couldn't afford anywhere near that though, claiming not to have a discretionary budget for this sort of thing, and offered me $2,000. They thanked me for coming to them first though," Green said. So he used a broker to find a buyer, and it turns out it was the Trump campaign.

With what he described as the "windfall" of cash from the sell, Green has been able to quit his job as a government contractor and focus on a solo legal practice and do some pro bono work.

Green also bought ClintonBiden.com and Cruz2016.com.
