Trump also met with Wilbur Ross, billionaire investor and chairman of WL Ross & Co. — and now, a leading candidate for the position of commerce secretary, according to CNN.

Sunday evening, it was another retired general who stood beside Trump outside that clubhouse door: Marine Corps Gen. John Kelly, the former head of U.S. Southern Command. While standing with Kelly, Trump was asked about his transition meetings — to which he replied: "We've made a couple of deals."

To this point, Trump has announced his picks for five key positions in his incoming administration. Here is NPR's running tally of his appointments so far.

Still, there was some other news of the president-elect's transition that did not revolve around that door in New Jersey. Trump confirmed to reporters that his wife, Melania, and 10-year-old son Barron would not be moving into the White House with him, at least at first. He said Melania and Barron would join him in Washington, D.C., "very soon — right after he finishes school."

The New York Post reports the two will continue to live in Trump Tower in New York City so that Barron can continue to attend his current private school.

"No official statement has been released by the Trump family regarding transition timing, but like any parents they are concerned about pulling their 10-year-old son out of school in the middle of the year," said transition spokesman Jason Miller. "We would also appreciate the same privacy and security considerations given to previous First Families with regard to minor children be extended to the Trumps as well."
