(AP) - A deal with Bill Clinton over his post-White House work helped clear the way for Hillary Rodham Clinton to join President-electBarack Obama's national security team as secretary of state, reshaping a once-bitter rivalry into a high-profile strategic and diplomatic union.

Obama was to be joined by the New York senator at a Chicago news conference Monday, Democratic officials said, where he also planned to announce that Defense Secretary Robert Gates would remain in his job for a year or more and that retired Marine General James L. Jones would serve as national security adviser.

The officials requested anonymity because they were not authorized to speak publicly for the transition team.

Bill Clinton's business deals and global charitable endeavors had been expected to create problems for the former first lady's nomination. But in negotiations with the Obama transition team, the former president agreed to several measures designed to bringtransparency to those activities.
