Organizers managing a campaign to write in President Joe Biden’s name for the New Hampshire primary are incensed at a fake robocall urging Democrat voters not to cast their ballots Tuesday.

The call, either an imitation or digital manipulation of Biden’s voice declares: “Voting this Tuesday only enables the Republicans in their quest to elect Donald Trump again. Your vote makes a difference in November, not this Tuesday,” NBC News reported.

On Monday, the Biden write-in campaign fired back.

“This is deep fake disinformation designed to harm Joe Biden, suppress votes, and damage our democracy,” Aaron Jacobs, a spokesperson for the write-in campaign, said in a statement.
