The U.S. Supreme Court on Monday tossed out the bribery conviction of former Virginia Governor Robert McDonnell, who was found guilty of accepting thousands of dollars in cash and gifts. And it spares McDonnell from having to report to prison to serve a two-year sentence. Prosecutors could seek to put McDonnell on trial again but with different jury instructions on the definition of corruption. But in sending the case back, the unanimous opinion cuts the heart out of the government's case against McDonnell. The ruling narrows the definition of "an official act," and in so doing would make it very hard for the government to retry the case.
