NEW YORK — President-elect Donald Trump and his team are battling back against charges of chaos and infighting as they race to set up an administration. The incoming Republican administration got an unlikely boost from outgoing Vice President Joe Biden, who said “no administration is ready on Day One.”

Trump stayed out of the public eye Wednesday, meeting with a stream of visitors at his New York skyscraper. But he took to Twitter to dispute reports of internal tension, declaring the transition operation was proceeding “so smoothly.”

Trump’s team said Wednesday night that it would be rolling out teams to interact with federal agencies during the transition, starting with national security advisers who would work with officials at the State, Justice, Defense and other national security departments.

They also said transition and administration officials would be required to sever lobbying ties and pledge that they will not lobby the government for five years after departing the Trump administration.

Trump’s team was essentially starting its transition planning from scratch after scrapping much of the preliminary work New Jersey Gov. Chris Christie conducted during the campaign. After winning the election, Trump demoted Christie and put Vice President-elect Mike Pence in charge.

The result has been a series of new additions to the transition team and several departures, mainly among those aligned with Christie.

Pence met Wednesday with Biden at the Naval Observatory, the vice presidential residence in leafy northwest Washington, D.C. Biden expressed confidence that by Trump’s Jan. 20 inauguration, “everything will be in good hands.”

Trump planned to meet Thursday in New York with Japanese Prime Minister Shinzo Abe, his first get-together with a world leader as president-elect. The State Department has said it had yet to hear from Trump’s transition team, raising the prospect of the Republican holding the meeting without any input from career diplomats with deep experience dealing with Japan.

Trump also plans to meet Thursday with an assortment of GOP officials, including former Secretary of State Henry Kissinger, Florida Gov. Rick Scott, South Carolina Gov. Nikki Haley and Texas Rep. Jeb Hensarling.

Trump aides and allies suggested some of the commotion within the transition team was to be expected given the enormous task at hand.

“The beginning of any transition like this has turmoil because it’s just the nature of the process,” former House Speaker Newt Gingrich said as he left Trump’s transition headquarters in Washington. He said the picture of Trump’s administration would become clearer over the next two or three weeks.

Former Michigan Rep. Pete Hoekstra, who has informally advised members of Trump’s national security team, blamed Trump’s detractors for the reports of drama.
