Fulton County District Attorney Fani Willis last week sought to have a special grand jury aid her investigation into the Republican leader's efforts to pressure officials in a state where he lost to Joe Biden.

The Fulton County Superior Court approved the request on Monday, according to a court filing. The grand jury will commence on May 2 and convene for up to a year.

A Trump spokesman did not immediately respond to a request for comment.

A Democrat, Willis launched the investigation after Trump was recorded in a Jan. 2, 2021, phone call pressuring Georgia Secretary of State Brad Raffensperger, a fellow Republican, to "find" enough votes to overturn his loss. Raffensperger declined.

The transcript quotes Trump telling Raffensperger: "I just want to find 11,780 votes," which is the number Trump needed to win Georgia. Trump has for months before and after the November 2020 election made false claims of voter fraud.

In a statement last week, Trump defended what he called his "perfect" phone call.

Legal experts have said Trump's phone calls may have violated at least three state election laws: conspiracy to commit election fraud, criminal solicitation to commit election fraud and intentional interference with performance of election duties. The possible felony and misdemeanor violations are punishable by fines or imprisonment.

In a recent court filing, Willis specifically mentioned that Raffensperger, whom she described as an "essential witness," had indicated he would only take part in an interview once presented with a subpoena.

In Georgia, a special grand jury can issue subpoenas forcing witnesses to testify but cannot issue indictments. Unlike a traditional grand jury, a special grand jury is devoted to just one case, making it a powerful investigative tool.
