“Yesterday the House passed their version of my bill to take on Uyghur slave labor in China 425 to 1,” Rubio tweeted. “But now Pelosi is blocking it from being sent to the Senate.”

The latest delay comes after weeks of legislative feuds over the Uyghur Anti-Forced Labor Act, which would prohibit imports that are connected to forced labor in China. Republicans say Democratic leadership has been stalling the bill for months due to the Biden administration’s concerns that the import ban would undermine climate negotiations with China.

House Minority Leader Kevin McCarthy (R., Calif.) in a Twitter post also accused Pelosi of “dragging her feet,” noting that the House “passed 30+ bills yesterday. All but ONE were sent to the Senate for a vote. It’s the Uyghur Forced Labor Prevention Act—which cracks down on goods made with Chinese slave labor.”
