The Denver district attorney’s office has opened an investigation into the leak of voting system passwords that were posted to a Colorado state website in June before being taken down last month.

The Colorado Secretary of State’s Office has hired a new law firm to investigate how passwords to Colorado’s voting machines ended up online. Attorneys Beth Quinn and J. Mark Baird with the law firm Baird Quinn LLC will look into the security breach.

The Denver district attorney has launched an investigation into how a spreadsheet of voting system passwords ended up on the Colorado secretary of state’s website earlier this year.

Secretary Jena Griswold said she'd hired an outside law firm to look into the incident. That won't satisfy her critics.

Last month, the Colorado Secretary of State’s Office said it inadvertently posted a spreadsheet to its website with a hidden tab including voting system passwords.

Trump campaign attorneys have demanded that Colorado Secretary of State Jena Griswold take immediate action to secure the state’s elections following the release of partial voting system passwords online.

The Colorado secretary of state issued a statement confirming that the partial passwords to its voting system were live on its website for a time.

Colorado officials said on Friday that the state’s elections are secure after a spreadsheet including a list of passwords used to access voting systems was inadvertently posted on the Secretary of State’s website.

The 2nd Judicial District Attorney's Office in Denver is investigating alleged violations of elections laws following the publication of voting machine passwords by the Colorado Secretary of State's Office during the run-up to the Nov.

Colorado Secretary of State Jena Griswold did not describe the incident as a threat to election integrity and said all passwords have been reset “out of an abundance of caution.”
