"Surprise", the first lady said as she later entered the Red Room, where handiwork with gumdrops was underway.

A tweeter pointed out their preference for the Obama family's display instead - which they suggest included 'much less white dead trees'.

It seems Trump is making good on his campaign and post-campaign promises to fight political correctness.

First Lady Melania and 11-year-old Barron Trump accepted the official Christmas tree from a Wisconsin farm and it was placed in the White House Blue Room on November 20.
More than 25,000 visitors are expected to tour the White House for the holidays and the kitchen is ready: 31,000 cookies have been baked, including 15,000 sugar cookies, many of which end up in purses for the trip home.
The 350-pound gingerbread house in the State Dining Room offers a view of the White House from the South Lawn, with wreaths on every window and a US flag flying from its sugary rooftop.
The guests were welcomed by Melania trump in a white dress by Dior and gold pumps - a way fully consistent with the festive mood settled these days in the White house.
