The NY Times has a story about how U.S. Telecom companies have been working with the NSA in providing data and routing information through U.S. based switches, allowing the Intelligence agency access to desired information.
Several officials said that after President Bush's order authorizing the N.S.A. program, senior government officials arranged with officials of some of the nation's largest telecommunications companies to gain access to switches that act as gateways at the borders between the United States' communications networks and international networks. The identities of the corporations involved could not be determined.
