WASHINGTON (AP) — The Senate is seeking to reverse a controversial law that allows farmers to harvest genetically modified crops even when the crops are caught up in legal battles.

The law, passed as part of a spending bill earlier this year, has become a flashpoint in the national debate over genetically engineered foods. It would expire at the end of the federal budget year next week, and a temporary spending bill passed by the House would extend it. But Senate Democrats’ spending bill would let it expire.
