One senior administration official said the administration thinks it’s making enough progress with companies that seeking legislation now is unnecessary. “We feel optimistic,” said the official, who spoke on the condition of anonymity to describe internal discussions. “We don’t think it’s a lost cause at this point.” Legislation, said Rep. Adam Schiff (D-Calif.), is not a realistic option given the current political climate. He said he made a recent trip to Silicon Valley to talk to Twitter, Facebook and Google. “They quite uniformly are opposed to any mandate or pressure — and more than that, they don’t want to be asked to come up with a solution,” Schiff said. Law enforcement officials know that legislation is a tough sell now. But, one senior official stressed, “it’s still going to be in the mix.” On the other side of the debate, technology, diplomatic and commerce agencies were pressing for an outright statement by Obama to disavow a legislative mandate on companies. But their position did not prevail.
