WASHINGTON (MarketWatch) — Ted Cruz is clashing with his fellow Republican senators over plans for a bill that would keep the U.S. government from shutting down next week.

Cruz, the Texas Republican, and other conservatives want to derail House Republicans’ plans to keep the government funded past Dec. 11. The Texan said he opposes a plan to pass a bill to keep the government funded through September, revisit Department of Homeland Security funding early next year and pass a proposal disapproving of President Barack Obama’s immigration policy. As Politico reports, some of his Senate colleagues say his plan would result in a government shutdown. “We’re just not going there,” said Sen. John Cornyn of Texas about revisiting anything like 2013’s shutdown fight, in which Cruz played a large role.
