A government watchdog group in Wisconsin has filed a lawsuit seeking to prohibit billionaire Elon Musk from ever again offering cash payments to voters in the battleground state like he did in this spring's hotly contested Supreme Court race.

A new lawsuit seeks to ban Elon Musk from handing out cash and asks a judge to declare the billionaire's activities to be bribery.

Elon Musk is being sued for allegedly implementing a "brazen scheme to bribe Wisconsin citizens to vote" in this year's state Supreme Court election.
