Obama Poised to Name New Defense, Treasury Chiefs

Alex Wong/Getty Images(WASHINGTON) -- With the "fiscal cliff" crisis behind him, President Obama is poised to name two new key players to his cabinet, with at least one announcement expected early next week.

The announcement of who will replace outgoing Defense Secretary Leon Panetta could come as soon as Monday, sources told ABC News.

Meanwhile, the president is also eyeing a replacement for outgoing Treasury Secretary Timothy Geithner, the longest-serving member of Obama's first-term economic team and one-time lead negotiator for the administration in the "fiscal cliff" talks.

Former Republican Sen. Chuck Hagel is a leading candidate to head the Department of Defense, while current chief of staff Jack Lew is the likely nominee for the top role at Treasury.

Geithner plans to depart his post "around the inauguration" Jan. 20, a Treasury spokesperson said Thursday, putting the department in transition just as the administration confronts the next "cliffs" over the automatic spending cuts and nation's debt limit.

During an appearance on ABC's This Week in April, Geithner said the next Treasury secretary would need to be someone who is "willing to tell [Obama] the truth and, you know, help him do the tough things you need to do."

Lew, a former two-time Office of Management and Budget director and trusted Obama confidant who has held the chief of staff role since early 2012, is the front-runner for the job.

Meanwhile, Sen. John Kerry -- Obama's nominee to replace outgoing Secretary of State Hillary Clinton -- has begun making more regular appearances at the U.S. State Department before his expected confirmation later this month.

His Senate hearings are set to begin shortly after Obama's inauguration, sources say. The administration still expects Clinton to testify about the Sept. 11 Benghazi, Libya, attacks before Kerry is confirmed.

But it is the potential nomination of Republican Hagel that has caused the most stir.

Critics from across the political spectrum have taken aim at the former senator from Nebraska's record toward Israel and what some have called a lack of experience necessary to lead the sprawling Pentagon bureaucracy or its operations. The controversy has set the stage for what would be a contentious confirmation process.

"A lot of Republicans and Democrats are very concerned about Chuck Hagel's position on Iran sanctions, his views toward Israel, Hamas and Hezbollah, and that there is wide and deep concern about his policies," Sen. Lindsey Graham, R-S.C., told Fox News Sunday.

He would not say whether Republicans felt so strongly as to expect a filibuster of the nomination.

"I can tell you there would be very little Republican support for his nomination," Graham said. "At the end of the day, they will be very few votes."

Still, Hagel, 66, a former businessman and decorated veteran who served in the Vietnam War, has won praise and admiration from current and former diplomats for his work on Obama's Intelligence Advisory Board and Panetta's Policy Advisory Board.

"Hagel is a statesman, and America has few of them," former U.S. ambassador to Iraq and Afghanistan Ryan Crocker wrote in a Wall Street Journal editorial this week.

"He knows the leaders of the world and their issues. At a time when bipartisanship is hard to find in Washington, he personifies it. Above all, he has an unbending focus on U.S. national security, from his service in Vietnam decades ago to his current position on the Intelligence Advisory Council," he said.

Obama defended Hagel in an interview last week, calling him a "patriot" who has done "extraordinary work" in public service, although he said he still had not made a final decision on who would head the Pentagon.

Other potential nominees for the DOD job include Michele Flournoy, former Under Secretary of Defense for Policy and a senior Obama campaign adviser for national security, and Ashton Carter, the current deputy secretary of defense.
