Free Flow of Information Act of 2007 - Prohibits a federal entity (an entity or employee of the judicial or executive branch or an administrative agency) from compelling a covered person (a person engaged in journalism, including their supervisor, employer, parent, subsidiary, or affiliate) to testify or produce any document unless a court makes specified determinations by a preponderance of the evidence.
Requires the content of compelled testimony or documents to be limited and narrowly tailored.
Applies this Act to communications service providers with regard to testimony or any record, information, or other communication that relates to a business transaction between such providers and covered persons. Sets forth notice requirements. Permits a court to delay notice to a covered person upon determining that such notice would pose a substantial threat to the integrity of a criminal investigation.
