By Jarrett Renshaw HARRISBURG, Pennsylvania (Reuters) -Billionaire Elon Musk promised on Saturday to give away $1 million each day until November's election to someone who signs his online petition, with the first prize awarded at a PAC event supporting Republican Donald Trump,

The giveaway is raising questions and alarms among some election experts who say it is a violation of the law to link a cash handout to signing a petition that also requires a person to be registered to vote.

Though maybe some of the other things Musk was doing were of murky legality, this one is clearly illegal,” wrote Richard L. Hasen, a law professor at the University of California, Los Angeles.

The tech billionaire kicked off the giveaways at a rally in Harrisburg on Saturday, handing a million-dollar check to a man named John Dreher.

The splashy move stakes out uncharted territory in American politics.
