Plainville — The survivor of an infamous Connecticut home invasion that left his wife and daughters dead says he's considering a lawsuit over a political advertisement linking him to Republican presidential nominee Donald Trump and "attacks on women and families."

Dr. William Petit is a Republican running for the state legislature from Plainville. On Wednesday he denounced 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." The group says the ad isn't personal. It's running identical advertisements using the names of other Republicans.

Petit's Democratic opponent is state Rep. Betty Boukus, who says she's horrified by the ad and wants it withdrawn.

Petit's wife and two daughters were killed in 2007.
