Missouri Attorney General Chris Koster will no longer accept campaign contributions from anyone under investigation by his office. He will also refuse to accept contributions from lobbyists, lawyers, or law firms who represent them. In addition, he will no longer take gifts of any value from registered lobbyists.

Koster announced the self-imposed policy last week after a New York Times report alleged he was influenced by lobbyists and campaign donations.

Attorneys general from around the country are now also considering possible voluntary changes in ethics policies.
