WASHINGTON (Reuters) – U.S. trade officials have asked for more information as they weigh whether to pursue a case against Chinese Internet restrictions that impede Google and other companies, an attorney for a U.S. free speech group said on Friday.

“They’ve asked us for more detail about it. We are trying to put that together right now,” said Gilbert Kaplan, a partner at King and Spalding, which represents the First Amendment Coalition, a nonprofit advocacy group.
