He endorsed the Republican presidential nominee and slammed Kamala Harris for her comments on 'reimagining' public safety.

'Tonight I am very pleased to welcome a man who has been an incredible champion, Trump said of Kennedy. 'We're both in this to do what's right for the country.'

'In honor of Bobby... I will establish a new independent commission on assassination attempts,' Trump - an assassination survivor himself - said.

'And we will release all the documents pertaining to the assassination of President John F. Kennedy.'

Trump floated a new policy after seeing demonstrators burn U.S. flags at protests in Chicago for the Democratic National Convention.

'They oughta make it illegal to burn the American flag,' Trump said, before suggesting a new law.

'You burn the American flag, you go to jail for one year,' he said to cheers.

The ex-president also bashed Vice President Kamala Harris's campaign - ripping her border policies.

'325,00 migrant children are missing, they are gone,' he said. 'She allowed them to be trafficked into this country.'
