Anything goes in the high-stakes game of world domination. Presidential hopeful Donald Trump has seen fit to use the name of Ireland’s very own Denis O’Brien in an attempt to discredit his nemesis, Hillary Clinton.

Mr. Trump issued an open letter on his website linking Ms. Clinton with Denis O’Brien’s less-than-diaphanous financial dealings around certain offshore places in Central America, the Caribbean and the Pacific Islands, among other high-profile issues.

Trump’s poison letter goes into exquisite detail about the sizeable donations that Mr. O’Brien has made to the Clinton Foundation, the funding for O’Brien-owned Digicel (a mobile phone provider that operates in 33 separate markets around Caribbean, Central America, and Oceania regions) for its Haiti operation, the Esat Digifone controversy, and of course, Siteserv, another of O’Brien’s business ventures that just happened to win the tender for the installation of hundreds of thousands of water meters across Ireland.

The missive, titled ‘Follow the money’ dubs the Irishman ‘another corrupt Clinton friend.’ Given Mr. O’Brien’s propensity to launch legal actions like a child throws tantrums, it’d be interesting to see if he’d take on the likes of Donald Trump.
