A stark disagreement over regulating AI in Republicans’ tax cut and spending bill is the latest tension among conservatives about whether to let states continue to put guardrails on emerging technologies or minimize such interference.

The United States Senate on Tuesday finally gave its green light to President Donald Trump’s tax bill, advancing legislation that locks in many of his key policy goals while adding $3.3 trillion to the national debt.

After critics called the bill a “get-out-of-jail-free card” for Big Tech that could make it nearly impossible to rein in social media platforms, Senator Marsha Blackburn killed her own compromise.
