A Democratic senator continues to block an amendment to a defense spending authorization bill Tuesday meant to protect state and local governments that reject anti-Israel boycotts.

The amendment was an outgrowth of the Combating BDS (Boycott, Divestment, Sanctions) Act of 2016, a bipartisan bill designed to protect state and local governments that divest from BDS-linked businesses. Senators Mark Kirk (R-Ill.), Ben Cardin (D-Md.), Chuck Schumer (D-N.Y.), and Joe Manchin (D-W. Va.) crafted a corresponding amendment in May to be included in the National Defense Authorization Act.
