The Department of Homeland Security (DHS) was warned by experts that voting machines were vulnerable to hackers and manipulation, a cybersecurity specialist said Monday.

Retired Col. Phil Waldron told a public hearing on election issues in Arizona that his team brought the information to DHS workers, including employees in the department’s cybersecurity office, known as CISA.
