Trump praises 'courage' of FBI to reopen Clinton email probe and 'right the horrible mistake that they made' as New Hampshire crowd screams 'Lock her up!'

A jubilant Donald Trump set off fireworks at a rally in Iowa as he celebrated the news that the FBI has reopened its investigation into Hillary Clinton's classified email scandal.

Speaking to excitable crowds during a campaign stop in Cedar Rapids, The Donald said 'justice will prevail'.

'The investigation is the biggest political scandal since Watergate, and it's everybody's hope that justice at last can be delivered,' he said. 'The FBI would never have reopened this case at this time unless it were a most egregious criminal offense.

'As you know, I've had plenty of words about the FBI lately, but I give them great credit for having the courage to right this horrible wrong.'
