Noem was on the short-list to be Trump's running mate
After a sweeping victory over Vice President Kamala Harris on Nov. 5, President-elect Donald Trump is now set to become just the second ever to serve nonconsecutive terms in office.
Trump has wasted no time in moving to assemble his team for a second term in the White House -- naming Susie Wiles as his chief of staff and New York Rep. Elise Stefanik as U.N. ambassador, among other positions.
Inauguration Day is Jan. 20.
President-elect Donald Trump is naming cabinet members and adding other key positions to his administration.
These team members will have a direct impact on implementing Trump's policies in his second term.

President-elect Donald Trump is expected to announce his intention to nominate Sen. Marco Rubio, R-Fla., for secretary of state, according to multiple sources familiar with the matter, ABC News reported.
Rubio, 53, has served in the Senate since 2011. He is currently the vice-chair of the Senate Select Committee on Foreign Intelligence and also sits on the chamber's Committee on Foreign Relations.
Several long-serving State Department officials tell ABC News they respect Rubio's extensive foreign policy experience and view him as unlikely to overly politicize the secretary of state role.
Rubio was also said to be favored for the role by Trump's chief of staff and veteran Florida political operative Susie Wiles, potentially helping the lawmaker edge out loyalists from the first Trump administration like former acting Director of National Intelligence Richard Grenell and former National Security Adviser Robert O'Brien.
Trump has asked Rep. Mike Waltz, R-Fla., to be his national security adviser, multiple sources said.
Waltz was at Mar-a-Lago on Monday, sources said.
The national security adviser is appointed by the president without confirmation by the Senate.
Waltz is a former Green Beret and China hawk who emerged as a key surrogate for Trump, criticizing the Biden-Harris foreign policy record during the campaign.
The Florida Republican sits on the Intelligence, Armed Services and Foreign Affairs committees.
He has supported aid to Ukraine in the past but has demanded "conditions," including increased spending from European allies, additional oversight of funds and pairing the aid with border security measures.
Waltz, who has visited Ukraine, was a vocal critic of the Biden administration's policy towards Ukraine, criticizing the White House and allies for not providing Ukraine with more lethal aid -- such as MiG fighter planes -- earlier in the conflict.
Before running for elected office, Waltz served in various national security policy roles in the Bush administration, Pentagon and White House.
Trump had four different national security advisers during his first term, outside of those who served very briefly: Michael Flynn, H.R. McMaster, John Bolton and Robert O'Brien.
Melania Trump is not expected to travel to Washington with President-elect Donald Trump on Wednesday, two sources told ABC News.
First lady Jill Biden had extended an invite to Melania Trump for a meeting, according to the sources. In 2016, Michelle Obama had hosted Melania Trump at the White House.
The Trump campaign declined to comment. ABC News has reached out to the first lady's office for comment.
