Casino executive Sheldon Adelson, who with his wife have given $36 million to super-political action committees in 2012, contributed $5 million to the host committee that helped stage the Republican National Convention in Tampa, Florida, in August, new Federal Election Commission reports show.
Among Adelson’s other donations is $10 million to Restore Our Future, the super-PAC backing Republican presidential nominee Mitt Romney.
Adelson is under federal investigation over charges that he violated the Foreign Corrupt Practices Act in connection with his casinos in Macau, a Chinese territory.
David Koch, executive vice president of Koch Industries Inc. and a major donor to conservative causes, contributed $1 million. Koch is chairman of Americans for Propserity Foundation, whose sister organization has said it plans to spend at least $125 million in support of Romney and other Republicans this year.
