Gov. Greg Abbott on Monday announced that the state has removed over 1 million names from the Texas voter rolls, mainly people who moved out of state or died but including 6,500 who Abbott described as potential noncitizens.

“Illegal voting in Texas will never be tolerated,” Abbott said in a statement. “We will continue to actively safeguard Texans’ sacred right to vote while also aggressively protecting our elections from illegal voting.”

Abbott added in a social media post that the removed names are being passed on to the attorney general’s office for possible criminal charges.
