The Campaign Legal Center has filed a complaint at the FCC against ABC-owned WLS-TV Chicago, saying it "ignored warnings" about violations of ad disclosure rules.
It joined with Common Cause and Sunlight Foundation to take aim at yet another station over its political files.
The complaint charges that the station refused to disclose the "true identity" of the sponsor of political ads run by Independence USA PAC even after the groups say they identified that funder as former New York mayor and current billionaire Michael Bloomberg.
"This is a knowing and willful violation of the law," said Campaign Legal Center policy director Meredith McGehee, "but more importantly failure to identify the true sponsor of the ad does a grave disservice to WLS viewers. They were left completely in the dark as to the fact that Michael Bloomberg, hiding behind a deceptively named organization, was spending large sums of money to influence their votes and the outcome of the election... If WLS is not willing to reveal the man behind the curtain, then we certainly hope the FCC will enforce long standing statutes and compel the station to do so in future."
