A warning has been issued by an anonymous whistleblower regarding a new online system for mail-in ballots. This system is untested and could potentially cause severe disruptions to elections.

The whistleblower's warning comes as a legal battle is underway in federal court over an executive order issued by Trump.

Further details about the potential risks and the ongoing legal battle are available from the source, which reports on the whistleblower's concerns about the impact on midterm elections.
