SAN FRANCISCO/MACAU, China (Reuters) - It's never good for the candidate when a big donor runs afoul of the law - as President Barack Obama learned this week: his campaign returned large donations from Chicago's Cardona brothers after it was reported that a third brother is a fugitive from U.S. drug and fraud charges.
Some Republican candidates for president could find themselves similarly embarrassed if criminal investigations against casino mogul Sheldon Adelson's Las Vegas Sands for violating the Foreign Corrupt Practices Act come to fruition before November.
