Benton Stevens and his dad Shane posted video on Facebook showcasing the hot chocolate stand in front of a shopping complex, selling for $2 a cup in Feb.
A sign in front of the boy's stand read, "Proceeds help Trump build the wall.""
For an extra 50 cents, Benton also offered large "Nancy Pelosi" marshmallows to melt. Smaller "Beto O'Rourke" marshmallows were also offered at no extra charge.

Stevens donated the proceeds to the nonprofit group We Build the Wall, Inc.
The GoFundMe campaign started by the group raised more than $22.9 million. They built a portion of the wall on private land. The group says that a half-mile long stretch of wall cost between $6 and $8 million to build.
