ATLANTA—Sidney Powell, a lawyer who played a leading role in the effort to reverse Donald Trump’s election loss in 2020, cut a deal to testify against the former president and others who Georgia prosecutors allege engaged in a “criminal enterprise” to subvert democracy.

A lawyer who was in Trump’s inner circle in the months after the November 2020 election, Powell pleaded guilty to misdemeanor charges Thursday in exchange for a sentence that avoids jail time. In open court, she admitted to orchestrating a scheme to access voting equipment in a rural Georgia county in hopes of substantiating conspiracy theories that voting machines were flipping votes.
