Early in his career, Levine was a top aide to former U. S. Senator Daniel Patrick Moynihan, Democrat from New York. In 2001, Levine joined the communications team of United States President George W. Bush.[4] Levine's main responsibility was to act as the "liaison between the White House and television networks."[1]
Levine was one of the first people to testify for the grand jury investigating the Plame scandal. Levine's testimony addressed his knowledge of White House procedures, in particular phone calls with reporters and a conversation he had with Karl Rove on July 11, 2003.[3] He testified again in October 2005, making him one of the last witnesses to speak to prosecutors before Patrick Fitzgerald decided not to indict Rove.[3] Levine's testimony to prosecution investigators indicated that the Plame affair was not a priority for Rove at the time and therefore easily forgotten by Rove.[6]
