Corey Lewandowski, who is expected to be offered a key position in the Trump administration, described the move as "amazing" and said it gave the Republican candidate the "spring in his step" he needed to win the race.
"With eleven days to go, something amazing happened," Mr Lewandowski said in a speech at the Oxford Union debating society on Wednesday evening.
"The FBI's director James [Comey] came out on a Friday and he said they may be reopening the investigation into Crooked Hillary's emails.
"What that did was remind people that there are two different rules in Washington - those of the elites, and the privileged and those for everybody else. (Actually what it did was to reinforce voter concerns that Hillary would be indicted, when that was never going to happen.)
"When Comey moved forward with that investigation... it allowed the campaign a little spring in their step, and for them to redouble their efforts."
So now we have the Clinton campaign and the Trump campaign essentially in agreement that James Comey helped steal this election from Hillary Clinton.
In my opinion this entire Trump "victory" is a sham that should be discounted entirely.
However I don't think we have a mechanism in place to do that, plus ANYTHING the Democrats do in response to all of this will be seen as a partisan attack and be dismissed by the media and the majority of Americans completely.
I think we are stuck with this outcome, and no petition or attempt to dismantle the electoral college is going to change that.
