The two main bills I'm aware of are the Decoupling America's AI Capabilities from China Act and No Adversarial AI Act. The former would have made it illegal for any American citizen to simply use DeepSeek. I couldn't find any lobbying data, but the obvious effect is that Americans would be forced to pay for more expensive domestic alternatives.
A House committee also recently probed Cursor and Airbnb for using Chinese models, rather than more expensive American alternatives. A sexagenarian Congressman gave a nonsense quote that he certainly did not come up with himself,[1] which sounds very similar to language Anthropic uses in its marketing materials.[2][3]
