Evan Vucci/AP President-elect Donald Trump's transition efforts have been slowed in part by a shakeup of his team shortly after Election Day.

President-elect Donald Trump’s staff on Thursday will name its team to start working with the national security agencies, including the departments of Justice, Defense and State, and the National Security Council, aides said Wednesday.

Additional teams will be named starting next week to coordinate with agencies dealing with economic policy, domestic policy and, finally, the independent agencies, said Republican National Committee strategist Sean Spicer.

Agency officials have reported that Trump’s transition staff has not yet made contact with them, a full week after his election and only about two months before his inauguration.

At least part of the delay was caused by Trump’s shakeup of his transition staff just days after the election. New Jersey Gov. Chris Christie, the original chairman, was replaced by Trump’s running mate, Indiana Gov. Mike Pence. The formal paperwork naming Pence was not delivered to President Barack Obama’s transition staff until Tuesday night.

Spicer also announced that Trump administration appointees would have to sign agreements not to work as registered lobbyists for five years after leaving their jobs. “People going out of government won’t be able to use that service to enrich themselves,” he said.

Trump is scheduled to continue meeting Thursday with people who are offering advice and possibly service to his administration, Spicer said, including former Secretary of State Henry Kissinger, National Security Agency Director Adm. Michael Rogers and South Carolina Gov. Nikki Haley.

MSNBC reported earlier Wednesday that Haley is a potential candidate for secretary of State.
