No wonder you dont know the whole truth, you got the news from Fixnews, or brietpuke.
The paintings are part of the “So You Want to See the President” series, which features different Americans, including political officials, waiting at the White House to meet with the president.
Politico reported that two people familiar with the matter said the family that owns the paintings wanted to reclaim them and their request was approved last year. Rockwell’s sketches originated from when he visited the White House in 1943. The prints were initially on display in the lower press hallway, but they were moved to the hallway between the upper press area and the Roosevelt Room during the presidency of George W. Bush. One of Rockwell’s works, “Working on the Statue of Liberty,” remains in the building. Director Steven Spielberg donated the painting to the White House during the Clinton administration.
So, yeah, no one can speak as to why!
