The article is not clear how or why the bust was sent back to the British Embassy.
That's because Breitbart is run by a bunch of lying liars who lie.
I have a feeling they didn't ask for it back. If they did specifically ask for it back you would think they (or the white house) would have said so.
The bust was specifically lent to George W. Bush, and was scheduled to be returned automatically at the end of his term. The British didn't have to ask for it back.
ETA: I get the feeling if the White house wanted the bust they could have kept it with one phone call to the British Embassy.
The White House has a bust of Churchill.
