George Steinbrenner blamed an illegal corporate campaign contribution to President Richard Nixon on bad legal advice. Newly released FBI documents show that Steinbrenner, then the owner of the Yankees, told FBI officials in 1979 that he would not have made the $25,000 donation had he known it was illegal. An FBI memo reports that Steinbrenner, who died last year, said that his lawyers should have been more thorough in their legal research.
