RICHMOND, Va. (AP) — Former Virginia Gov. Bob McDonnell says he knows in his heart he’s innocent of the federal corruption charges he’s facing. The former governor finished his third day of testifying Friday at federal court in Richmond by proclaiming his innocence and saying he would never corrupt his office in exchange for gifts. 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. McDonnell said he had thought Williams was a true friend and accused him of making false statements in court. The former governor is expected to resume testifying on Monday.
