President Barack Obama formally introduced Denis McDonough as his chief of staff on Friday, describing his deputy national security adviser as not only a straight-shooter, but also a close friend.
Obama debuted McDonough, whom the president had been widely expected to select, at the White House, saying he had been "counting on Denis for nearly a decade."
McDonough, a longtime adviser to Obama who has advised the president largely on matters of national security, succeeds outgoing chief of staff Jack Lew. The president has nominated Lew to become the next secretary of the treasury.
President Obama introduces Denis McDonough as the new White House chief of staff, saying the former deputy national security adviser was chosen for the job because of "his dedication, his determination."
"He's the consummate public servant who plays it straight," the president said. "And that's the kind of teamwork that I want in the White House."
Of McDonough's national security advice, Obama said: "Denis has played a key role in every major national security decision in my presidency."
McDonough's ascension coincides with a broader staff overhaul at the White House. Among the changes included elevating White House communications director Dan Pfeiffer to a senior adviser role; Jennifer Palmieri, Pfieffer's deputy, takes over that role. Rob Nabors, the director of legislative affairs, was promoted to a deputy chief of staff position. Miguel Rodriguez takes over that role.

Obama also singled out his longtime political adviser, David Plouffe, whose last day at the White House is on Friday, for praise.
"David has been with me from the start of this enterprise, running for president," Obama said, adding: "If it were not for him, we would not have been as effective as a White House, and I probably wouldn't be here."
