(AP) — Members of the Kansas congressional delegation seem to agree the coming weeks are critical to the future of the federal health care law. But the all-Republican delegation is less certain about how to stop it.

Sen. Pat Roberts wants to delay the law’s October implementation. He told a meeting of the Kansas Independent Oil and Gas Association on Monday it’s difficult to take away a subsidy once it’s been granted.

Rep. Mike Pompeo says the tactic of defunding the law by refusing to pass an appropriations bill may shut down government for a few days. But Pompeo also said he’s unsure if the tactic would be useful if Republicans fold on the issue a week later.

U.S. Rep. Lynn Jenkins say Congress will probably pass another continuing resolution to fund government.
