The chairman of the Democratic National Committee wrote there is a greater chance of being struck by lightning than witnessing in-person voter fraud, in a blistering op-ed criticizing President Trump's voter fraud panel.

"You're more likely to see someone fatally struck by lightning than witness a case of in-person voter fraud," Tom Perez wrote.

Perez called the panel a "propaganda factory" that uses taxpayer money to suppress votes and wage "war on voters."

"This isn't a war on voter fraud. It's a war on voters – and it's only being waged by Republicans," Perez added.

After claiming millions of noncitizens cast a ballot in the 2016 election, President Trump called for the voter fraud panel to study vulnerabilities in the voting systems that could lead to voter fraud and examine concerns about voter suppression, along with other voting irregularities.

The panel has faced stiff opposition from Democrats, including Perez, who say the panel was created to suppress minority voters in an effort to bolster Republican candidates.

Forty-five states have refused to comply with the panel's request for voter rolls, which includes the full names of all registered voters, their addresses, dates of birth, the last four digits of their Social Security numbers, voting history and other personal information.

California, Kentucky, Virginia, Massachusetts, and Connecticut have signaled resistance to the request citing concerns over privacy, and House Democrats have called for the removal of Kansas Secretary of State Kris Kobach's removal as vice chairman of the panel, claiming he has made false statements about voter fraud.

Perez pledged Democrats would launch a legal fight against what he views as the panel's voter suppression efforts and through the DNC's Civic Engagement and Voter Participation Department and Voting Rights Institute.

"As Republicans try to trample on our most sacred freedoms, Democrats will do everything we can to end discrimination and protect the one right that preserves all others — the right to vote," Perez said.
