Earlier, the Washington Post also reported on the substance of the calls.
In the recording, Mr Trump can be heard telling the investigator to find proof of election fraud in Georgia before “the very important date," referring to the 20 January inauguration of president Joe Biden.
Now, CNN has cited a Georgia official as saying that the recording of the audio was located in the trash folder of Ms Watson’s device.
It was also reported that officials in Georgia earlier claimed the recording of the call didn’t exist.
The leaked audio is more proof of the former president’s extraordinary attempts to convince officials to help him find evidence for his baseless claims of voter fraud.
Mr Trump also told Ms Watson that he hoped "we" could win Georgia and that "you have the most important job in the country right now.".
Later, in January, Mr Trump called and pressured the Republican secretary of state Brad Raffensperger to find evidence of voter fraud. »
