The former chairman of Colorado's Republican Party was charged with forgery and voter fraud for allegedly forging his wife's mail-in ballot for the 2016 election, a local Fox News affiliate reported late Tuesday.

Steven Curtis, who was the chairman of the state party from 1997 to 1999, was charged on Feb. 1 with one count of forgery of a public record, a fifth-degree felony, and an elections mail-in ballot offense, which is a misdemeanor. Curtis is accused of filling out his wife's ballot and forging her signature.

Curtis has remained active in Colorado politics and oversaw the Denver Tea Party Patriots advisory board in 2011. He is also a local AM radio talk show host.

Last fall, ahead of the 2016 election, Curtis had knocked Democrats as the party associated with voter fraud.

“It seems to me,” Curtis said in a 42-minute segment of his KLZ 560 show, “that virtually every case of voter fraud I can remember in my lifetime was committed by Democrats.”

The Weld County district attorney’s office has opened an investigation into Curtis and filed a criminal complaint on Feb. 1, the Denver Post reported.

Curtis is due back in court in May.

Voter fraud became a hot topic during and immediately following the 2016 election, during which President Trump repeatedly warned of voter fraud and later doubled-down on the idea, suggesting without evidence that voter fraud cost him the popular vote to Democratic nominee Hillary Clinton Hillary Diane Rodham ClintonHillicon Valley: FBI chief says Russia is trying to interfere in election to undermine Biden | Treasury Dept. sanctions Iranian government-backed hackers The Hill's Campaign Report: Arizona shifts towards Biden | Biden prepares for drive-in town hall | New Biden ad targets Latino voters FBI chief says Russia is trying to interfere in election to undermine Biden MORE.

Shortly after his inauguration, Trump called for a "massive investigation" of voter fraud, which has not taken place.
