Zuckerberg group faces more pressure: CREDO Mobile, a mobile service provider that lobbies on progressive issues, has gathered about 40,000 signatures on a petition asking prominent members of Mark Zuckerberg’s immigration reform lobbying group, FWD.us, to drop out over ads the group funded that support conservative politicians.

Some environmental groups are complaining that FWD.us has funded television ads supporting politicians who back construction of the Keystone XL oil pipeline and proposals to drill for oil in the Arctic National Wildlife Refuge. The ads do not mention immigration reform but support politicians who may be able to help ease immigration proposals through the Senate.

Tesla and PayPal co-founder Elon Musk and Yammer chief executive David Sacks withdrew support from the group Friday, and CREDO mobile is asking others, such as Yahoo chief executive Marissa Mayer and LinkedIn co-founder Reid Hoffman, to also withdraw from the group.
