HEY BERNIE! THERE'S A KNIFE IN YOUR BACK!

Wikileaks posted emails Friday that suggested the DNC was favoring Clinton over her rival Sen. Bernie Sanders during the primary season, prompting Clinton’s campaign to point to a massive hacking of DNC computers in June that cybersecurity firms linked to the Russian government.

Clinton campaign chairman John Podesta added fuel to the debate Monday, saying there was “a kind of bromance going on” between Russian President Vladimir Putin and Trump. The Clinton campaign says Russia favors Trump’s views, especially on NATO.

Donald Trump on Monday dismissed as a “joke” claims by Hillary Clinton’s campaign that Russia is trying to help Trump by leaking thousands of emails from the Democratic National Committee.

“The new joke in town is that Russia leaked the disastrous DNC e-mails, which should have never been written (stupid), because Putin likes me,” Trump wrote as part of a series of Tweets.

The hacking enraged die-hard Sanders supporters who have long claimed that the DNC had its finger on the scale throughout the primaries. The disclosures prompted the resignation of DNC chairwoman Debbie Wasserman Schultz on the eve of the party’s convention in Philadelphia, where Clinton is expected to officially accept the nomination for president.

It wasn’t immediately clear how WikiLeaks received copies of the internal Democratic emails.

Democratic Party officials learned in late April that their systems had been attacked after they discovered malicious software on their computers. A cybersecurity firm they employed found traces of at least two sophisticated hacking groups on the Democrats’ network – both of which have ties to the Russian government. Those hackers took at least one year’s worth of detailed chats, emails and research on Donald Trump, according to a person knowledgeable of the breach who wasn’t authorized to speak publicly about the matter
