Russian hackers have launched an attack on the New York Times and other U.S. news organizations, according to a CNN report, which states that U.S. officials have been briefed on the matter. The FBI is also investigating the hacking attempts.

Investigators think that Russian intelligence is behind the attacks, which are part of a broader effort to attack the Democratic Party. Earlier this year, the released of DNC emails resulted in accusations that the party plotted against Bernie Sanders and resulted in the resignation of Debbie Wasserman-Schultz, the DNC chair.

Many believe that the Kremlin is deliberately trying to swing the U.S. election, because Vladimir Putin likes Donald Trump and likely feels he can more easily control the Republican nominee than Hillary Clinton, the Democratic nominee who is currently leading the polls. Trump has welcomed the hacks, and in July invited the Russians to conduct more attacks against U.S. entities: “I will tell you this, Russia: If you’re listening, I hope you’re able to find the 30,000 emails that are missing. I think you will probably be rewarded mightily by our press.” He later claimed it was a joke.

The Kremlin, for its part, has denied that it is conducting cyber attacks against the United States, but most experts believe that Putin is indeed behind the effort to undermine the U.S. election. Trump has also denied that he is friends with Putin, saying he didn’t even know who Putin was — which seems highly unlikely to say the least, considering Trump’s extensive business ties to Russia.
