When were the words 'so help us God' removed from the World War 2 memorial at Arlington National Cemetery?

The Words "so help us God" were removed from the World War II Memorial at Arlington National Cemetery in 2013. This decision followed a lawsuit filed by the American Humanist Association, which argued that the phrase represented a violation of the separation of church and state. The removal was part of a broader effort to ensure that memorials and monuments are inclusive to people of all beliefs.
