From the Atlanta Journal-Constitution:

The Fulton County special grand jury investigating potential criminal interference in Georgia’s 2020 elections has subpoenaed key members of former President Donald Trump’s legal team, including his personal lawyer Rudy Giuliani, according to copies obtained by The Atlanta Journal-Constitution.

In addition to Giuliani, those being summoned include John Eastman, Cleta Mitchell, Kenneth Chesebro and Jenna Ellis, all of whom advised the Trump campaign on strategies for overturning Democrat Joe Biden’s wins in Georgia and other swing states.

The grand jury also subpoenaed U.S. Sen. Lindsey Graham (R-S.C.), one of Trump’s top allies, along with attorney and podcast host Jacki Pick Deason.
