President-elect Donald Trump seemingly compared the United States to Nazi Germany in a tweet Wednesday morning after an unverified document of apparent opposition research leaked the night prior through news organizations.

"Intelligence agencies should never have allowed this fake news to 'leak' into the public," Trump posted. "One last shot at me.Are we living in Nazi Germany?"

The report, allegedly created by a British intelligence officer and published in full by Buzzfeed without verification, put forth a number of allegations about Trump's connections with Russia. Among those allegations was that that Trump once paid prostitutes in Russia to urinate on a bed once slept in by President Barack Obama, which was caught on tape by Russian intelligence and used as leverage by the Kremlin.

"Russia has never tried to use leverage over me. I HAVE NOTHING TO DO WITH RUSSIA - NO DEALS, NO LOANS, NO NOTHING!" Trump posted in response Wednesday morning, before the Nazi Germany tweet.

Trump is scheduled to hold a press conference Wednesday, during which it is almost certainly to be asked further about the unverified report. Thus far, he's taken to Twitter to respond angrily, which culminated in the Nazi Germany tweet. He even noted that Russia had denied the claims. Kremlin spokesman Dmitry Peskov told reporters it was "complete fabrication and utter nonsense."

The unverified report had apparently been floating around intelligence and media circles before it was alluded to in a CNN article Tuesday that said Trump and Obama had been briefed on the report. In fact, Sen. John McCain, R-Arizona, even passed the information along to FBI Director James Comey last month, according to the Guardian. Buzzfeed ultimately published the report in full Tuesday night. 

Trump has long had issues with the U.S.' intelligence agencies over their assessment that Russia hacked the Democratic National Committee and took other actions during the presidential election in an effort to help Trump get elected over his opponent, Democrat Hillary Clinton.
