South Carolina's Supreme Court agreed to hear an appeal by MarkMeadows to block a Georgia grand jury subpoena demanding his testimony in a probe of possible criminal interference in the 2020presidential election.

The Supreme Court took the case almost a month after a South Carolina judge orderedMeadows to comply with a subpoena from a grand jury in Georgia.

He is scheduled to testify in an Atlanta courthouse on November 30th. The South Carolina Supreme Court may not allow that.

The grand jury is looking into efforts by former President Donald Trump and his allies to convince Georgia election officials to reverse their 2020 loss to President Joe Biden.

The call between Trump and Georgia Secretary of State Brad Raffensperger was recorded by a former congressman. A joint session of Congress will meet to certify Biden's win in the Electoral College.

Georgia authorities had to ask a judge in South Carolina to force him to comply with the subpoena because he lives in Georgia.

The spokesman for the Fulton County District Attorney's Office had no comment on the Supreme Court's action.

James Bannister argued in his application to the Supreme Court that the subpoena should be blocked because it violates his client's constitutional right to privacy.

The South Carolina law protectsMeadows from being forced to travel out of state to testify.

A grand jury that does not issue indictments or conduct procedures in secret cannot be considered a true grand jury.
