What started as a widely backed proposal to locate a new Smithsonian American Women’s History Museum on the National Mall devolved into a partisan fight Thursday after Republicans revised the legislation to ensure no transgender people are included in the exhibits.

The House rejected the bill, 204-216, an outcome that leaves the next steps uncertain. The revised bill also would ban a “diversity” of views and give President Donald Trump the final say on where the museum would be located.

“It was a simple bill. You kind of ruined it with your trans obsession and your culture wars,” Rep. Teresa Leger Fernandez, a Democrat from New Mexico and chair of the Democratic Women’s Caucus, said earlier in the week.

But Republicans argued it was Democrats who were overreacting to the changes and now threatening progress toward establishing the long-sought women’s museum in the nation’s capital.

Republican Rep. Nicole Malliotakis of New York, the bill’s chief sponsor, said “it’s a disgrace” that Democrats would be standing in the way of the bill’s passage.

“Perhaps the party that is opposing a women’s history museum on the National Mall because they want to have transgender exhibits — maybe they are the ones who are trans obsessed,” Malliotakis said.

In the final tally, a handful of Republicans voted against the bill, joining Democrats who led the opposition. The chamber came to a standstill as GOP leaders scrounged for support from their ranks.
