The federal government has released a list of all of the entities helping to pay for President Trump's lavish White House ballroom, according to reporting by Business Insider. Big tech is all over this thing, with companies like Amazon, Apple, Google, Meta and Microsoft all shelling out cash to fund the 90,000-square-foot ballroom.It's not just big tech. Defense firms are also helping to pony the bill here. Companies like Lockheed Martin and Palintir are sending some cash, as are random billionaires like the Winklevoss twins and Domino Sugar magnate Jose Fanjul. The list reads like a who's who of the ultra wealthy and connected.As we all know, giant corporations and billionaires are kind and selfless, but what if just this one time they want something in return for their largesse? Columbia professor of law Richard Briffault told Time that most of these donors have done "significant" business with the federal government, raising ethical concerns."I doubt it's a literal quid-pro-quo, but it's probably more like if you give this, I will look favorably upon you.' Or maybe more like, if you don't give this, after you've been asked, I won't [look favorably upon you]," Briffault said. "It's greasing the system by making contributions, and in some ways, his leaning on them for contributions is quasi-coercive."Noah Bookbinder, CEO and President of ethics watchdog organization Citizens for Responsibility and Ethics in Washington said the whole thing is extraordinarily unusual, deeply disturbing and does have tremendous ethics implications." He also said that "Donald Trump has made very clear over the years that he does appreciate people paying tribute to him, and he does tend to do things that benefit those people."
