MADISON, WI (WTAQ) - Wisconsin’s public indoor smoking ban took effect a year ago on Tuesday.

Governor Scott Walker has criticized the ban in the past – but today, he said he won’t try to change it.

When he ran for office last year, the Republican Walker said it hurt the rights of private business owners – but he never did promise to repeal the ban.

Health advocates say it’s done a great job of improving Wisconsin’s indoor air quality.

The law limits smoking in all businesses and government facilities where the general public is allowed.

Walker said Thursday he has listened to people throughout Wisconsin about the subject – and it’s become clear to him that the smoking ban works. And therefore, the governor said he would not support a repeal of it.
