A probe into a controversial political mailer is making progress. The investigation, which began about eight months ago, has identified a printing and mailing company in McAllen as the source of the mailer's production. Further details about the case are available from local news sources.

A man from Edinburg is now involved in the investigation, and a judge has ordered him to provide documents and testify. The mailer in question was distributed to homes in a specific district, where a city commissioner was running for election. The commissioner had launched the probe after the mailer was sent out.
