A Georgia prosecutor has opened a criminal investigation into attempts by former President Donald Trump to have the results of the state's presidential election results overturned.

Fulton County prosecutor Fani Willis sent a letter Wednesday to several state government officials, including Secretary of State Brad Raffensperger, asking them to preserve records related to a Jan. 2 phone call from Trump, according to the New York Times.

Most of Atlanta is in Fulton County, where a jury could be hostile to Trump. He received just 26% of the vote there.

On the call, Trump said Raffensperger needed to "find 12,000 votes." President Joe Biden won the state's 16 electoral votes by roughly that margin. 

Trump spent two months after Nov. 3 attacking Raffensberger and Gov. Brian Kemp. He accused them of not doing enough to find voting fraud he baselessly claimed changed the outcome. Georgia officials certified the presidential election results in three separate counts.

Trump's second impeachment trial opened Monday. He is also facing potential legal problems elsewhere.

At least two investigations into Trump are underway in New York state. Manhattan district attorney Cyrus Vance Jr. is investigating criminal fraud allegations, while New York attorney general Letitia James is conducting a civil fraud inquiry.

On Monday, Raffensperger's office opened an administrative inquiry into Trump's phone call. The phone call, which was recorded and made public, prompted some Democrats to call for impeachment hearings.
