Democrats on the Senate Commerce Committee are fuming at Sen. Ted Cruz, R-Texas, for delaying authorization of the Spectrum and National Security Act.

Senate Majority Leader Chuck Schumer, D-N.Y., said Cruz is fighting "petty partisan culture wars" over the bill, while Commerce Committee Chair Maria Cantwell, D-Wash., said Cruz caused the committee to delay markup of legislation that would extend subsidies for high-speed internet, according to The Hill.

Cruz has insisted on modifications to the bill that would gut bipartisan amendments Cantwell negotiated with Sen. Roger Wicker, R-Miss., Cantwell told The Hill.

According to The Hill, Cruz had proposed modifications for existing amendments because Cantwell would not allow Republicans to offer new amendments to the bill, citing a GOP source. Cantwell knew for months what changes Cruz wanted to the legislation, The Hill said.
