New Mexico governor Susana Martinez admitted that her paternal grandparents came to the U.S. illegally, and this admission has prompted a bit of indignant Tweeting.

I know they arrived without documents, especially my father's father, Martinez said in an interview on Wednesday with KLUZ-TV, Univision's Albuquerque affiliate, the Associated Press reported.

People have already taken to Twitter with the news.

Susana Martinez is the New Mexico Voldemort, one person Tweeted. An agenda to oppress/regulate a race from their own hidden & shared ethnic past.

UH-Oh!Anchor Baby alert! another person Tweeted.

Martinez only recently found out her grandparents' immigration status, her spokesperson Scott Darnell said.

It's unfortunate that some are choosing to personally attack the governor, but these tactics prove that supporters of giving driver's licenses to illegal immigrants have run out of legitimate defenses for a bad policy, Darnell said, the AP reported.

Martinez's grandparents came to the U.S. in the 1920s.

In those days, the law was much different, she said, the Albuquerque Journal reported.

Martinez has been criticized by immigrant groups for having tried to repeal a New Mexico law that allows illegal immigrants to obtain driving licenses. The bill was rejected earlier this year.
