A judge on Wednesday ordered former House Speaker Newt Gingrich to testify before a special grand jury in Atlanta that's investigating whether then-President Donald Trump and others illegally tried to influence the 2020 election in Georgia.

Gingrich, who lives in northern Virginia, had argued that the federal law that normally requires states to honor out-of-state grand jury summonses should not apply in this case because the special grand jury lacks the power to indict. He also argued that the subpoena would be unnecessarily duplicative and burdensome because he has already agreed to testify in front of a congressional select committee investigating the deadly Jan. 6 attack on the Capitol and that his testimony in both matters would essentially be the same.
