Texas Attorney General Ken Paxton, whom Ortega cast her ballot for in a 2014 election, helped in the prosecution.
“This case shows how serious Texas is about keeping its elections secure, and the outcome sends a message that violators of the state’s election law will be prosecuted to the fullest,” he said, Fox News reported.
Ortega testified that she wasn’t aware of the rights granted to citizens and the rights granted to residents.
“My mom just used us to get stamps. She never gave us love or guidance. She got deported,” she said. “All my life since I worked, I always on my knowledge thought I was a U.S. citizen because I never knew the difference of U.S. citizen and U.S. resident. And the point is if I knew, everything would’ve been the correct way.”
