Donald Trump has vowed to release classified documents relating to the assassination of John F. Kennedy within days of taking office.

He made the latest assurance at his victory rally on Sunday ahead of the inauguration in Washington D.C. on Monday.

'It's all going to be released,' he said, keeping with a pre-election promise he made to 'restore transparency and accountability to government.'

The promise was one of the key takeaways from his rally, which saw thousands of Americans wait in the blistering cold and snow to get a glimpse at Trump and his key allies.  

The 78-year-old president-elect said he is bringing an end to ‘four years of decline’ under a ‘failed’ President Joe Biden in a speech less than 24 hours before he is sworn in for the second time.

After the crowd watched performances from Kid Rock and a speech from Hollywood actor Jon Voight, Trump said: ‘People are happy. It’s been a long time. None of this could have been possible without you.’

He celebrated winning the popular vote, sweeping the seven battlegrounds and the seismic shift in support in all 50 states in his defeat over Vice President Kamala Harris.

The crowd at Donald Trump’s rally went absolutely wild when he announced that the documents on John F. Kennedy’s assassination will be made public within the first days of his administration.

'As a first step toward restoring transparency and accountability to government, we will also reverse the overclassification of government documents,’ Trump vowed at his pre-inauguration rally on Sunday.

He continued: ‘And in the coming days we're going to make public remaining records relating to the assassinations of President John F. Kennedy, his brother Robert Kennedy, as well as Dr. Martin Luther King Jr. and other topics of great public interest. It's all going to be released.'

Robert F. Kennedy Jr., Trump’s incoming Secretary of Health and Human Services, pushed for him to pledge to make these documents public – especially those related to his uncle and father.
