An anti-immigrant activist has filed a lawsuit challenging the citizenship of Arizona State Representative-elect Raquel Téran (D-Phoenix) — but has no evidence to support the claim.

The Arizona Republic reported that Alice Novoa, a perennial GOP candidate and conspiracy theorist, filed a lawsuit against Téran in Maricopa County Superior Court the day before the general election claiming the Democrat is not qualified to hold office because she is “not a legal citizen of the United States.”

“This is obviously upsetting,” the newly-elected state representative wrote after being served papers on Thursday night, “but not surprising.”

Novoa’s suit “is just another attempt to silence me and the community I fight for,” Téran wrote.

The report noted that Novoa has promoted a theory claiming immigrants are involved in a “secret plot” to reclaim the Southwest on behalf of Mexico.
