The President-elect has travelled to his Palm Beach estate in Florida for the holiday, and acknowledged that America has “just finished a long and bruising political campaign”.
In his Thanksgiving message, he said: “Emotions are raw and tensions don’t just heal overnight.
An announcement is forthcoming about my role in helping to make America great again. https://t.co/jGRyzFRBAK

“It’s my prayer that on this Thanksgiving we begin to heal our divisions and move forward as one country strengthened by shared purpose and very, very common resolve.”
Mr Trump also tweeted: “Happy Thanksgiving to everyone. We will, together, MAKE AMERICA GREAT AGAIN!”
Earlier he gave two jobs to Republican women who had criticised him during his campaign. He is also said to be considering offering Mitt Romney – one of his most fierce critics – the most senior post of secretary of state.
The billionaire on Wednesday picked South Carolina governor Nikki Haley as US ambassador to the UN and charter school advocate Betsy DeVos to lead the department of education.
Both were critical of his campaign, with Ms Haley urging voters to “reject the siren call of the angriest voices”.
The 44-year-old is a daughter of Indian immigrants and took Mr Trump to task over his rhetoric about illegal immigration during his campaign.
In July, Ms DeVos said: “A lot of the things he has said are very off-putting and concerning.”
She heads the American Federation for Children and is former chairwoman of the Michigan Republican Party.
Mr Trump is expected to pick billionaire investor Wilbur Ross to lead the commerce department. The 78-year-old is chairman and chief strategy officer at private equity firm WL Ross & Co.
Retired neurosurgeon Ben Carson, who stood as a Republican candidate for the presidential election, has been tipped to become secretary of housing and urban development and tweeted on Wednesday “an announcement is forthcoming about my role in helping to make America great again”.
He said: “I feel that I can make a significant contribution particularly to making our inner cities great for everyone.”
Mr Trump’s spokesman, Jason Miller, said he would now focus on his choice for secretary of state. Mr Romney is said to be in consideration along with former New York mayor Rudy Giuliani.
The billionaire will be sworn into office in less than 60 days and has hundreds of high-level administration posts to fill.
