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. The DA’s office on Monday would not divulge additional details of the probe beyond confirming an open investigation.

The Denver district attorney's office has opened an investigation into the leak of voting system passwords that were posted on a state website for months leading up to the election and only taken down last month.

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.”

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.

Colorado officials said 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.

The Denver District Attorney’s Office confirmed with FOX31 on Monday that the office is investigating passwords to Colorado election systems that were found to be posted online for months. However, the agency will not comment more about the investigation,
