WASHINGTON (AP) — President Barack Obama is likely to name Denis McDonough, one of his closest national security advisers, as his next chief of staff, according to people familiar with the White House thinking.

However, White House officials say a final decision has not been made.

In tapping McDonough, Obama would be relying on an inner circle ally for the key West Wing post. McDonough, 43, currently serves as the president's deputy national security adviser and is highly regarded by Obama and White House staffers.

McDonough would replace current White House chief of staff Jack Lew, the president's nominee for treasury secretary.

The people familiar with the White House thinking spoke on condition of anonymity because there has been no announcement an appointment.

Before his tenure in the White House, McDonough served as Obama's main adviser on foreign policy issues during the 2008 presidential campaign. Earlier, he worked as a foreign policy specialist in Congress, including as a senior foreign policy adviser to former Senate Majority Leader Tom Daschle, D-S.D.

McDonough would be Obama's fifth chief of staff. Rahm Emanuel, William Daly and Pete Rouse, as interim chief of staff, preceded Lew in the job.
