The former head of President Donald Trump’s recently disbanded election integrity commission has charged two people with double voting in Kansas and Colorado during the 2016 election.

Kris Kobach, Kansas’ secretary of state, announced Thursday that Bailey Ann McCaughey and Que J. Fulmer are facing accusations involving voter fraud.

McCaughey allegedly voted in Colorado and Finney County, Kan., where Garden City is located, and is facing charges of election perjury and voting more than once.

Fulmer is accused of voting in Colorado and just across the border in Hamilton County, Kan. Fulmer has been charged with two counts of voting without being qualified, one count of voting more than once, and one count of advance voting unlawful acts, Kobach’s office says.

The Colorado Secretary of State’s Office says it has notified the county clerks in Douglas and Adams counties about the cases for possible referral to local prosecutors for further investigation after tying McCaughey and Fulmer’s voting records there. A spokeswoman for the office said both appear to have registered as Republicans in Colorado.

“Stopping voter fraud is one of the most important things the Secretary of State’s office can do,” Kobach said in a written statement. “These prosecutions will help deter voter fraud in the future.”

On Wednesday, Trump announced that he was disbanding his Presidential Advisory Commission on Election Integrity — headed by Kobach — following a wave of tumult enveloping the panel. The president created the commission after alleging that millions voted illegally in the 2016 presidential election, despite a lack of evidence.

In Colorado, the commission prompted thousands of voters to withdraw their registrations rather than have their identifying information sent to the Trump administration.
