(CNN) The NRA is going after the long-time animated children's television show "Thomas & Friends."

NRA TV host Dana Loesch appeared on the association's TV show, "Relentless" and slammed "Thomas & Friends" for partnering with the United Nations to increase diversity on the program.

Last month the show introduced two new female characters, one of which was painted with an African-inspired face and is voiced by actress Yvonne Grundy, who is originally from Kenya.

The UN's website says the UN partnered with the animated series to "teach children the importance of taking part in the global efforts to end poverty, providing girls and boys with the same opportunities, and of course doing so while protecting our planet."

Loesch slammed the iconic "Thomas & Friends" characters and then showed them on screen wearing Ku Klux Klan hoods while on flaming train tracks.
