David Pecker, the former publisher of the National Enquirer, testified Monday in front of the grand jury weighing former President Donald Trumps potential indictment.

Manhattan District Attorney Alvin Bragg is investigating the former presidents involvement in paying $130,000 of hush money to adult film actress Stormy Daniels, who alleged during his 2016 presidential campaign they had an affair in the early 2000s. Bragg has brought in nine witnesses throughout the investigation, according to The New York Times .

Pecker had also testified in January. In 2018, he was granted immunity in the case after providing testimony about Trumps role in the hush money sent to Daniels.
