A mystery is brewing at the White House about what happened to the oak tree President Donald Trump and French President Emmanuel Macron planted there last week.

The sapling was a gift from Macron on the occasion of his state visit, Axar.az informs citing AP.

By the end of the week, however, the tree was gone from the White House lawn. A pale patch of grass was left in its place.

The White House has not offered an explanation.

The oak sprouted at a World War I battle site that became part of US Marine Corps legend.

About 2,000 US troops died in the June 1918 Battle of Belleau Wood, fighting a German offensive.
