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.

Senator Marsha Blackburn removed the AI moratorium from President Trump's bill. The original provision banned states from enforcing AI laws for 10 years, later revised to 5 years. Blackburn's amendment to remove the moratorium passed with an overwhelming majority.
