MADISON, Wis. (AP) _ Gov. Scott Walker says he now believes there's a chance President Barack Obama could delay implementation of his signature federal health care law in response to political pressure from both Republicans and Democrats.

Walker is an ardent opponent of the law and has repeatedly called for it to be repealed. He spoke about it again Tuesday in response to questions following a speech at the annual Wisconsin Counties Association meeting.

Walker says he doesn't think Obama would ever agree to repeal the law, major portions of which take effect in January.

But he says Obama's decision to delay the employer health insurance mandate coupled with Democratic Sen. Max Baucus calling the law a potential ``train wreck'' in April could lead to Obama slowing further implementation.
