WASHINGTON (AP) — President Barack Obama says some Republicans have an “ideological fixation” with stopping his health care law and that they have no plan to help millions of uninsured Americans.

At a news conference Friday, Obama defended his recent one-year delay in the law’s employer coverage requirement as a “tweak” that will ultimately help implement the legislation with fewer disruptions for businesses.

Obama chastised some Republicans who advocate a government shutdown this fall as a last-ditch effort to block the rollout of coverage for the uninsured. He says that’s a “bad idea” that will weaken the economy as a recovery is getting traction.

The president says that health care politics have gotten so overheated that the discussion of “Obamacare” doesn’t take place in a normal atmosphere.
