PLAINVILLE, Conn. (AP) A political action committee says it'll stop running an advertisement linking the survivor of a Connecticut home invasion to Republican presidential nominee Donald Trump.

Dr. William Petit is a Republican running for the state legislature from Plainville. On Wednesday he threatened to sue over the internet advertisement, which was paid for by the Labor United for Connecticut political action committee.

The group's ad reads, ``Stop Donald Trump and Republican William Petit's attacks on women and families.''

Petit's wife and two daughters were murdered in the 2007 attack. His Democratic opponent is state Rep. Betty Boukus (BOH'-kis), who says she's horrified by the ad.

The union group says the ad wasn't personal. It's running identical ads using the names of other Republicans. It says the ad's run was scheduled to end Wednesday and won't be renewed.
