President Donald Trump announced he will address the nation on Thursday night, focusing on election security and voting machines. This comes amidst efforts by an administration task force to declassify documents related to these topics.

Trump has frequently claimed that U.S. voting systems, including mail-in ballots, are insecure and susceptible to fraud, despite winning two presidential elections himself. On Tuesday, he hinted at revealing substantial information, stating, “Our country has to shape up,” and referring to it as a “big announcement.”

The prime-time speech may cover additional subjects, but Trump did not specify them. The “big news” he has suggested might relate to election processes, particularly the 2020 presidential election, which he has often accused of being fraudulent without evidence.

Sources familiar with the task force’s efforts revealed that part of the focus is on reforming election systems and shedding light on the Russia investigation from Trump’s first term. The task force aims to release sensitive government documents to the public.
