RICHMOND, Va. (AP) _ After an emotional day of testimony, former Virginia Gov. Bob McDonnell will be back on the stand in his public corruption trial. McDonnell testified Thursday about his strained marriage before answering questions about thousands of dollars in gifts and loans he and his family received from a wealthy vitamin entrepreneur. He’ll answer more questions from his lawyer Friday. It’s unclear when prosecutors will begin cross-examination. McDonnell and his wife, Maureen, are charged with accepting more than $165,000 from former Star Scientific Inc. CEO Jonnie Williams in exchange for promoting his products. Their marriage is a key element to the defense, which has suggested the couple couldn’t have conspired because they were barely communicating.
