It's a rare occurrence. Casino mogul and Republican financier Sheldon Adelson made a public appearance on Thursday, questioned before a judge for hours.
Adelson, chairman and chief executive officer of the Las Vegas Sands Corporation, is being sued by Hong Kong businessman Richard Suen.
Suen believes Adelson owes him millions after he provided help in opening a casino in Macau.
Adelson told a jury he doesn't owe anyone for the success of his Macau casino, which is his real moneymaker these days.
Suen is suing for $328 million over a business deal from 2001. Suen said he made it possible for Adelson to get a license to build the casino by arranging a meeting between Sands Corporation executives and Beijing officials.
Adelson said his meetings with Suen didn't affect his ability to obtain a license because they are distributed by Macau officials rather than those on the mainland.
The trial came to a halt when Suen's attorneys called for a mistrial. Adelson pulled out a stack of books and brochures he said show his business was so successful he didn't require Suen's help.
"I didn't need Richard or anybody else to tell us that we were qualified in the convention industry. It turned out that's (the casino) what Macau wanted," Adelson said.
The judge denied the mistrial request but asked the jury not to consider the materials when making a decision.
This is not the first time Adelson and Suen have shared a courtroom. In 2008, Suen was awarded millions of dollars following a lengthy trial over the same issue. The Nevada Supreme Court overturned the ruling in 2010.
Adelson's testimony is set to resume on Friday.
