Koch legal work

A report Sunday about Washington lawyer Robert Bennett’s work for Koch Industries incorrectly said its executives were spending up to $1 million on an ad campaign against first lady Hillary Rodham Clinton in the New York Senate race. The money is being raised by a political action committee formed by the Citizens for a Sound Economy, a Washington-based think tank founded by Koch family foundations. Koch officials say, however, that neither the company nor family members have given money to the PAC or a related political fund.
