Atlanta-area prosecutors investigating efforts to overturn the 2020 election results in Georgia are in possession of text messages and emails directly connecting members of Donald Trump’s legal team to the early January 2021 voting system breach in Coffee County, sources tell CNN.

Fulton County District Attorney Fani Willis is expected to seek charges against more than a dozen individuals when her team presents its case before a grand jury next week. Several individuals involved in the voting systems breach in Coffee County are among those who may face charges in the sprawling criminal probe.

Investigators in the Georgia criminal probe have long suspected the breach was not an organic effort sprung from sympathetic Trump supporters in rural and heavily Republican Coffee County – a county Trump won by nearly 70% of the vote. They have gathered evidence indicating it was a top-down push by Trump’s team to access sensitive voting software, according to people familiar with the situation.
