ST. PAUL-- A political group is stopping activity amid mounting criticism over a mailer that tried to link an increase in shootings with a black St. Paul mayoral candidate.

The committee called Building a Better St. Paul announced Friday it would stop its political activity and donate the rest of its funds to a nonprofit.

The group was behind a mailer sent to voters which said more than 100 shots were fired in the city since guns were stolen from the home of candidate Melvin Carter.

The group says in a statement that the mailer was misguided. Carter's campaign called it racist.

The St. Paul police union was among groups that donated to Building a Better St. Paul. The union leader says it's stopping all political activities for the rest of the election season.
