Hillary Clinton's campaign chairman John Podesta is facing more trouble with hackers.

On Wednesday night, Podesta's Twitter account sent out a pro-Donald Trump tweet.

"I've switched teams. Vote Trump 2015. Hi pol," the account tweeted.

The tweet was quickly deleted, but not before reporters caught sight of it.

Clinton's spokesman Nick Merrill later confirmed to reporters in Las Vegas that Podesta's Twitter account had been hacked.

It's been a bad week for Podesta, whose hacked emails were being released in batches by WikiLeaks.

Podesta has said that the hacking of his Gmail account is being investigated by the FBI, which suspects it was done by groups with Russian ties.
