California Gov. Gavin Newsom pushed back on President Trump’s assertions that vote-by-mail elections lead to widespread voter fraud.

“There’s been study after study — don’t take my word for it, don’t take the president’s — study after study that just lays claim to no evidence whatsoever that there’s widespread voter fraud,” Newsom said Wednesday on NBC’s Today show. “We want to prepare to keep people safe and allow them to have their constitutional rights protected, constitutional right to vote, without putting their health at risk.”
