Questions surround Obama nominee's contractor ties

President Obama's pick for undersecretary of defense has drawn questions about his business ties.

WASHINGTON (CNN) - The head of the Senate Armed Services committee said Thursday that he needed more information on how the nominee for deputy secretary of defense would handle conflicts of interests in his Pentagon post.

President Obama has nominated William Lynn, an undersecretary of defense during President Clinton's second term, to be deputy to Secretary Robert Gates.

Lynn was a senior vice president at Raytheon, which has billions of dollars in Defense Department contracts. It is is the maker of the Army's Patriot missile system and the Navy's Tomahawk missile and is developing a global positioning satellite communication system for the Air Force.

As deputy secretary, Lynn would be involved in the process of budgeting and acquisitions, in addition to running the day-to-day operations of the Defense Department.
