Perhaps you remember Sheldon Adelson from the way he single-handedly propped up Newt Gingrich's campaign for a few months earlier this year. Or maybe you remember him from his $100 million pledge to Mitt Romney, or Sarah Silverman's $100 million pledge to him. But maybe you should know something else about Sheldon Adelson. ThinkProgress says:

Things are getting awkward for Sheldon Adelson, the casino magnate who pledged to spend a “limitless” amount of money to get Mitt Romney elected. Adelson’s latest woes stem from business practices surrounding his lucrative casino in Macau, the only Chinese city with legalized gambling.

The Macau operation has long been under scrutiny but a new in-depth investigation from ProPublica and PBS focused on allegations of improper, and perhaps in some cases illegal, business dealings by Adelson’s Las Vegas Sands company in China.

Adelson has a long, dirty history with China. Which means that Mitt's claims that he's going to get tough on China as president are being funded in part with Chinese money. Even morally compromised former Republican presidential candidate John McCain thinks this is wrong.
