America PAC, into which Musk has poured $75 million, is racing to convince voters to turn out to polls on Nov. 5 and vote for the Republican nominee. But four people involved in the group’s outreach told Reuters that it is facing issues in key battleground states such as Wisconsin and Nevada.

Elon Musk donated nearly $75 million to a super PAC backing Donald Trump from July to September, according to a new filing out Tuesday.
