A bill to name a federal courthouse in Tallahassee after Justice Joseph W. Hatchett, the first Black man to serve on the Florida Supreme Court — sponsored by the state’s two Republican senators and backed unanimously by its 27 House members — was set to pass the House with bipartisan support. And then, Republicans pulled their backing with no explanation and ultimately killed the measure. Asked what made him vote against a measure that he had co-sponsored, Representative Vern Buchanan, Republican of Florida, was brief and blunt: “I don’t know,” he said. This is today's Republican Party.
