Colorado Secretary of State Wayne Williams said he planned to supply publicly-available data to the panel, which says it wants to investigate ballot fraud.
Voters' names and addresses will be given to the White House commission. Dates of birth and social security numbers won't be.
The lawsuit was filed Monday in Fulton County Superior Court by the Coalition for Good Governance and voters who are members of the group.
"We will provide publicly available information," Wayne Williams says, but not Social Security numbers, driver’s license numbers, or full dates of birth.
Wayne Williams says the state's voting system has not been targeted by Russian hackers, and he stands by the election results.
The decentralized nature of the state’s election system makes such a feat extremely unlikely.
