Last week, Attorney General Alberto Gonzales, a Republican, gave a speech saying that data retention by Internet service providers is an "issue that must be addressed." Child pornography investigations have been "hampered" because data may be routinely deleted, Gonzales warned.

Now, in a demonstration of bipartisan unity, a Democratic member of the Congressional Internet Caucus is preparing to introduce an amendment--perhaps during a U.S. House of Representatives floor vote next week--that would make such data deletion illegal.

Colorado Rep. Diana DeGette's proposal (click for PDF) says that any Internet service that "enables users to access content" must permanently retain records that would permit police to identify each user. The records could not be discarded until at least one year after the user's account was closed.
