Election officials in Florida, Missouri and West Virginia said Monday they are pulling out of a bipartisan, multistate effort aimed at ensuring the accuracy of voter rolls that has come under the crosshairs of conspiracy theories fueled by Donald Trump’s false claims about the 2020 presidential election.

The system to thwart voter fraud, known as the Electronic Registration Information Center, or ERIC, has become a target of suspicion among some Republicans after a series of online posts early last year questioning its funding and purpose.

Louisiana withdrew last year and Alabama is in the process of doing so. Missouri Secretary of State Jay Ashcroft said Monday he pressured the group to address his and others’ concerns.

It appears that ERIC will not make the necessary changes to address these concerns, which is why it is time to move on, Ashcroft said in a statement.

West Virginia Secretary of State Mac Warner said he did not expect the exit from the program to affect his states’ ability to maintain accurate voter rolls. Florida’s secretary of state, who is appointed by the governor, did not immediately respond to a request for comment.

Shane Hamlin, the group’s executive director, confirmed that the three states had announced their cancellation.

Election conspiracies fuel the dispute over the voter fraud system

We will continue our work on behalf of our remaining member states to improve the accuracy of U.S. voter rolls and increase access to voter registration for all eligible citizens, Hamlin said in a statement.

The program was started in 2012 by seven states and has been bipartisan since its inception, with four of the founding states led by Republicans. After the states officially leave, participation will be limited to 28 states and the District of Columbia.

The withdrawals have frustrated state election officials involved in the effort, who said the departure demonstrates how deeply election conspiracies have spread across the Republican Party.

Election officials retiring from ERIC primarily harm their own states’ ability to accurately maintain their voter rolls,” Michigan Secretary of State Jocelyn Benson said in a statement to the Associated Press Monday. “It’s strange and disturbing to me that an official would choose to validate false information about being part of a partnership whose sole and vested purpose is to improve the integrity of our elections.

Not all Republican-led states have re-evaluated their participation in the program. In a recent AP survey of participating states, eight Republican-led or controlled said they had no intention of leaving.
