Those who sign the petition, which pledges to support free speech and gun rights, must provide their contact information so that AmericaPAC may contact them about their vote.

Musk, who has emerged as a major Trump supporter in recent years, founded AmericaPAC in July with the aim of supporting the former president's campaign.

So far he has donated $75m (£57.5m) to the group, which has quickly become a central player in Trump's campaign.

The Trump campaign relies heavily on outside groups like AmericaPAC to turn out voters.

A statement on the group's website said: “America PAC was founded to support these key values: secure borders, secure cities, sensible spending, fair justice system, free speech, right to self-protection.”

Musk said he wants to “get over a million, maybe two million voters in the battleground states to sign the petition in support of the First and Second Amendments.”

“I think it sends a critical message to our elected leaders,” he added.

According to US business magazine Forbes, Musk is currently the richest man in the world with an estimated net worth of $248 billion (£191 billion).

Seven key states are likely to be contested in the 2024 presidential race, including Pennsylvania as well as Wisconsin, North Carolina, Georgia, Michigan, Arizona and Nevada.
