Republican Rep. Nancy Mace introduced legislation to ban trans women from using single-sex bathrooms on Capitol Hill, targeting Rep.-elect Sarah McBride, the first openly trans member of Congress. Here's what the bill says and what the reaction has been.

Just two weeks after Democrat Sarah McBride made history by becoming the first out trans person elected to Congress, a House Republican has introduced a resolution that would ban trans women from using women’s bathrooms in the U.S. Capitol.

McBride, the first out transgender person elected to Congress, will serve in the House starting next year, and Mace doesn't want her using women's bathrooms at the Capitol.
