A controversial episode of the PBS children's program "Postcards from Buster" will air at 4:30 p.m. today on KQED-Channel 9.

Anyone familiar with the gentle "Postcards from Buster" will be amazed that a show about an animated bunny is at the center of a political storm.

Buster, a spin-off character from "Arthur," travels with his father, an airline pilot, to various parts of the country. He makes video postcards of his adventures, showing real-life people from the Hmong to cowgirls.

This episode, which has agitated incoming U.S. Secretary of Education Margaret Spellings, features a Vermont family — an 11-year-old girl with lesbian parents. The point of the episode, "Sugartime," is to show how maple syrup is harvested.

Upon learning of the content, Spellings demanded the Department of Education's seal be removed from the episode and all references to the department's funding for the program hidden.
