MADISON, Wis. — A group of former assistant Wisconsin attorneys generals are attacking Republican Attorney General Brad Schimel as he fights for re-election.

Schimel's opponent, Democrat Josh Kaul, released a letter Monday signed by 45 assistant attorneys general.

The letter ticks off a number of Kaul talking points, including delays in testing sexual assault evidence kits and Schimel's decisions to challenge former President Barack Obama's administration's environmental regulations and buy promotional coins.

Kaul spokeswoman Gillian Drummond says the signers drafted the letter and gave it to Kaul. She says the signers include at least 10 who worked for Schimel and 20 who served under his predecessor, Republican J.B Van Hollen.

Schimel campaign manager Johnny Koremenos says it's no surprise Kaul can find "like-minded activists." He noted 63 Wisconsin sheriffs have endorsed Schimel.
