'All hell has broken loose': Inside Elon Musk's high-stakes pro-Trump door-knocking effort

Nine Republican operatives and canvassers connected to the Elon Musk-backed America PAC say they're worried the high-profile grassroots operation on behalf of Donald Trump’s presidential bid may hamper his chances in states decided by slim margins.

America PAC has been tasked with much of the pro-Trump canvassing operation as his campaign focuses its efforts on a more limited effort targeting so-called low-propensity voters.

But the people who spoke to NBC News said the operation may not be the well-oiled machine many in the party might hope it is.

America PAC ended relationships this summer with two other prominent GOP -aligned canvassing firms that were knocking on doors as part of its effort.

America PAC has spent upward of $54 million on Blitz , more than the PAC has on the three other vendors combined.

The PAC has a “random audit program” to guard against fraud, a source says.

A former state House candidate in Arizona who knocked for the PAC in multiple states before the group fired her shared audio she recorded that was first shared with Reuters from an Oct. 8 training session in Wisconsin .

Two canvassers who spoke with NBC News said they were made to knock in North Carolina as Hurricane Helene rolled in.

Another person familiar with the effort dismissed the concerns and said the America PAC canvassing effort is a well-oiled machine.
