Usher releases a t-shirt with a message

Usher has launched a limited edition collection of t-shirts slamming US presidential hopeful Donald Trump.

The R&B star has teamed up with the commerce platform Teespring to sell the shirt in four forms including t-shirt, tank, and hoodie. The shirt will be available until July 5.

The garments come in various shades of green and are priced from $15 to $25.

Proceeds from sales of the shirt will be split evenly between Pencils of Promise, a non-profit organization working to improve children's access to quality education in the developing world, and Usher's New Look program, which trains youth in leadership development.

The shirt can be purchased exclusively at https://teespring.com/DontTrump
