US President Donald Trump invited Americans in North Carolina to vote twice in presidential elections, in person and by mail, to check the security of the electoral system, The Guardian reported.

“Let them send it in and let them go vote,” Trump said in an interview with WECT-TV in Wilmington, North Carolina, on Wednesday when asked about the security of mail-in votes. “And if the system is as good as they say it is then obviously they won’t be able to vote” in person.

“President Trump outrageously encouraged” North Carolinians “to break the law in order to help him sow chaos in our election,” said the state attorney general, Josh Stein, in a tweet. “Make sure you vote, but do NOT vote twice! I will do everything in my power to make sure the will of the people is upheld in November.”
