A mailer sent out over the weekend touts Assemblywoman Cheryl Brown's pro-environment credentials, calling her an "environmental champion" who will "protect our environment."It was sent by independent expenditure committee Keeping Californians Working, which last week reported receiving nearly $2 million in contributions, including $1 million from Chevron. It claims Brown (D-San Bernardino) helped pass a major solar energy bill and stronger renewable energy and efficiency requirements.But some environmental groups, including one named in the mailer, say she doesn't deserve those plaudits.A campaign mailer sent by the Keeping Californians Working independent expenditure committee hit Assembly District 47 voters over the weekend."I think it's completely outrageous that our name is being used in a mail piece to imply that we have endorsed Assemblymember Cheryl Brown," said Strela Cervas, co-director of the California Environmental Justice Alliance, which was referenced in the piece and has not made an endorsement in the competitive race between Brown and Democratic challenger Eloise Reyes.Cervas said the group's score card shows that Brown is not an environmental justice leader "by any stretch of the imagination."In a statement, Brown's campaign manager said her record on the environment is "unmatched" and touted her endorsement by the California Democratic Party, adding that she can't control the actions of the independent expenditure committee.Brown has received criticism in the past for her role in helping block a key oil provision in last year's SB 350, the landmark climate change bill that would have cut petroleum use statewide by 50% over 15 years.Keeping Californians Working could not be reached for comment. It has reported spending just under $42,000 in campaign mailers for Brown.
