The jury is set to hear from the final witness in the public corruption trial of former Virginia Gov. Bob McDonnell and his wife, Maureen. U.S. District Judge James Spencer says at least one more rebuttal witness will testify Thursday. Closing arguments are expected Friday. The McDonnells are charged with taking more than $165,000 in gifts and loans from former Star Scientific Inc. CEO Jonnie Williams in exchange for promoting his company’s dietary supplements. The defense has suggested the McDonnells’ marriage was so fractured that they couldn’t have conspired with each other. Bob McDonnell testified that their communication was perfunctory, at best, as he avoided his wife to escape her anger. Williams testified under immunity that he spent lavishly on the McDonnells only to secure their help.
