Trump's fantastic real estate deal in 2006 with Russian billionaire  Dmitry Rybolovlev:

“Maison de l’Amitie,” or the House of Friendship. It was the trophy of a Boston-area magnate, until he lost his fortune in 2004. That’s when Donald Trump scooped it up. After paying $41 million for the place in November 2004, Trump called it “the finest piece of land in Florida, and probably the U.S.” ......Trump had no intention of living there. He intended to flip it for a quick—and huge—profit. His initial asking price, less than two years after buying it, was $125 million. By the time Trump listed the property, in early 2006, the real estate market was already cooling off.... In the summer of 2008, Trump found a solution to his problem in the form of one of the world’s hundred richest men: a 41-year-old Russian billionaire named Dmitry Rybolovlev....

Dmitry Rybolovlev, 'hostage to Putin',  struck it rich with Uralkali, Russian potash corporation. Bloomberg News:

Even though Russian billionaires are part of the international jet set, with homes throughout the world and yachts and planes that can take them anywhere at any moment, they are invested in Russia's fate. Does that mean that they would do anything to change Russia's political course, which has driven down the value of their domestic holdings? I don't think so. These men are hostages to President Vladimir Putin's regime, which demonstrates that fact on a regular basis....

Trump and Dmitry Rybolovlev frequently wind up in the same places at the same time.

Two Trump Companies discovered in Cyprus in 2016.

Trump's Secretary of Commerce Wilbur Ross owns 18% of the Bank of Cyprus, he is the largest shareholder.

The second largest shareholder in Bank of Cyprus is a Russian conglomerate called Renova Corp., which is founded and headed by Viktor Vekselberg, a Russian billionaire and associate of Putin.

The third largest owner of the Bank of Cyprus is Russian billionaire Dmitry Ryboloviev. Yes, the same Russian billionaire who bought the Florida property from Trump in 2006.

The Bank of Cyprus is known as a money laundering site for Russian and EU money.

Other Russian connections, and lies about those connections, of the Trump administration.

Trump's Attorney General Sessions lied in his Senate hearings about his 2016 contacts with the Russian Ambassador to the US, Washington Post - Sessions met with Russian envoy twice last year, encounters he later did not disclose:

One of the meetings was a private conversation between Sessions and Russian Ambassador Sergey Kislyak that took place in September in the senator’s office, at the height of what U.S. intelligence officials say was a Russian cyber campaign to upend the U.S. presidential race.

Prior to taking office, Trump's National Security advisor had discussions about Russian sanctions with the Russian Ambassador Kislyak assuring him that relations would improve with Mr. Trump. the conversations were wiretapped and recorded by US Intelligence. Flynn lied to the FBI about these conversations and was let go only after his lies were leaked and exposed in the media. NYT:

On Jan. 2, administration officials learned that Mr. Kislyak — after leaving the State Department meeting — called Mr. Flynn, and that the two talked multiple times in the 36 hours that followed. American intelligence agencies routinely wiretap the phones of Russian diplomats, and transcripts of the calls showed that Mr. Flynn urged the Russians not to respond, saying relations would improve once Mr. Trump was in office, according to multiple current and former officials.

Of course, those Trump administration financial connections with Russian billionaires in shady banks, lies about Russian contacts, lack of tax returns for Mr.Trump, are all probably not suspicious, or as serious as a private email server...right? Or do we need a special prosecutor to sort this out?  As even Republican Darrell Issa has called for, 4 days ago (but has since retracted...a new account in Cyprus perhaps?)
