Members of the LGBTQ community have held a parade in Washington to promote the rights of sexual minorities in the face of US President Donald Trump's public denial of their rights.

The event will also bring more than 9,000 soldiers from around the country to Washington, about 7,000 of whom will march in the parade itself. The event will also include at least eight Army bands, and some troops will ride on the nearly three dozen horses and two mules expected to march as part of a historical section of the parade.
