WASHINGTON (AP) — The Senate on Thursday voted to limit the amount of government subsidies the wealthiest farmers receive when purchasing crop insurance.

The vote was one small victory this week for critics of a massive, five-year farm bill that would cost almost $100 billion a year and includes generous subsidies for the nation’s biggest crops. Supporters have deflected other attempts on the Senate floor to reduce government help for agriculture, including proposals to trim sugar subsidies and crop insurance.
