The anti-Sanders messages are included with mostly run-of-the-mill messages about upcoming Democratic events that WikiLeaks selected for release Wednesday.
One caller objects to Sanders' choices for the party's platform committee and doesn't even want the Vermont senator to have a speaking slot at the Democratic National Convention.
The caller - speaking about Sanders - says "he's not a Democrat. Please stop this man now." Another complains about the role given to Sanders supporter Cornel West, who's been highly critical of President Barack Obama.
The release follows more than 19,000 stolen DNC emails that WikiLeaks published on its website last week.
The latest release, which came in the middle of the Democratic National Convention where Hillary Clinton was officially named the party's presidential nominee, is the second batch in a series that has deeply rattled the party and prompted the organization's chairwoman, Debbie Wasserman Schultz, to step down.
