The Supreme Court also threw out the corruption conviction of former Virginia Governor Bob McDonnell, in a case that could make it harder to prosecute public officials for corruption. McDonnell and his wife were accused of accepting more than $175,000 in loans, vacations and luxury products in exchange for providing favors to Jonnie Williams, a businessman seeking to promote his diet supplement business. But in a ruling written by Chief Justice John Roberts, the court narrowed the definition of what constitutes corruption, saying it applies to formal activities, like filing a lawsuit or making an official determination, and not to acts like arranging meetings, hosting parties or calling officials to discuss Williams’ business.
