Trump's Ties to Russia--with sources

Trump has become 'an unwitting agent of the Russian Federation'
Ex-director of the CIA publicly states that Putin has be successful in manipulating Trump - "In the intelligence business, we would say that Mr. Putin had recruited Mr. Trump as an unwitting agent of the Russian Federation."

Trump campaign worked to undermine support for Ukraine
Throughout the campaign, Trump has been dismissive of calls for supporting the Ukraine government as it fights an ongoing Russian-led intervention. Trump’s campaign chairman, Paul Manafort, worked as a lobbyist for the Russian-backed former Ukrainian president Viktor Yanukovych for more than a decade.
Still, Republican delegates at last week’s national security committee platform meeting in Cleveland were surprised when the Trump campaign orchestrated a set of events to make sure that the GOP would not pledge to give Ukraine the weapons it has been asking for from the United States.

Trump states he doesn't believe Putin will invade the Ukraine - after Russia has already annexed Crimea
“He’s not going into Ukraine,” Trump said. “He’s not going to go into Ukraine. You can mark it down. You can put it down. You can take it anywhere you want.” “He’s already there isn’t he?” Stephanopoulos said. “Well, he’s there in a certain way,” Trump said.

Trump has been unclear on his relationship with Putin
In an interview with ABC News in August 2016, Trump said he had "no relationship with Putin." In an interview with MSNBC in 2013, Trump said "I do have a relationship, and he's very interested in what we're doing."

Unexplained server connection between Russian bank and Trump Organisation
“I have an outlier here that connects to Russia in a strange way,” he wrote in his notes. He couldn’t quite figure it out at first. But what he saw was a bank in Moscow that kept irregularly pinging a server registered to the Trump Organization on Fifth Avenue. “I’ve never seen a server set up like that,” says Christopher Davis, who runs the cybersecurity firm HYAS InfoSec Inc. and won a FBI Director Award for Excellence for his work tracking down the authors of one of the world’s nastiest botnet attacks. “It looked weird, and it didn’t pass the sniff test.”

Russian diplomats and officials were in touch with Trump's team throughout the campaign
Russian government officials conferred with members of Donald Trump’s campaign team, a senior Russian diplomat said Thursday, a disclosure that could reopen scrutiny of the Kremlin’s role in the president-elect’s bitter race against Hillary Clinton. The statement came from Deputy Foreign Minister Sergei Ryabkov, who said in an interview with the state-run Interfax news agency that “there were contacts” with the Trump team. “Obviously, we know most of the people from his entourage,” Ryabkov said.

Ex-Trump campaign chairman allegedly received undisclosed cash payments from pro-Russian Ukranian party
Handwritten ledgers show $12.7 million in undisclosed cash payments designated for Mr. Manafort from Mr. Yanukovych’s pro-Russian political party from 2007 to 2012, according to Ukraine’s newly formed National Anti-Corruption Bureau. Investigators assert that the disbursements were part of an illegal off-the-books system whose recipients also included election officials.

Trump advocates Russian hacking
Donald J. Trump said on Wednesday that he hoped Russian intelligence services had successfully hacked Hillary Clinton’s email, and encouraged them to publish whatever they may have stolen, essentially urging a foreign adversary to conduct cyberespionage against a former secretary of state.
“Russia, if you’re listening, I hope you’re able to find the 30,000 emails that are missing,” Mr. Trump said during a news conference here in an apparent reference to Mrs. Clinton’s deleted emails. “I think you will probably be rewarded mightily by our press.”

Russia was involved in passing along hacked information about the Clinton campaign to Wikileaks
Officials briefed on the matter were told that intelligence agencies had found that individuals linked to the Russian government had provided WikiLeaks with thousands of confidential emails stolen from the Democratic National Committee (DNC) and others.
"The U.S. Intelligence Community (USIC) is confident that the Russian Government directed the recent compromises of e-mails from US persons and institutions, including from US political organizations. The recent disclosures of alleged hacked e-mails on sites like DCLeaks.com and WikiLeaks and by the Guccifer 2.0 online persona are consistent with the methods and motivations of Russian-directed efforts. These thefts and disclosures are intended to interfere with the US election process. Such activity is not new to Moscow—the Russians have used similar tactics and techniques across Europe and Eurasia, for example, to influence public opinion there."
In early May, the DNC called in CrowdStrike, a security firm that specializes in countering advanced network threats. After deploying their tools on the DNC’s machines, and after about two hours of work, CrowdStrike found “two sophisticated adversaries” on the Committee’s network.
CrowdStrike linked both groups to “the Russian government’s powerful and highly capable intelligence services.” APT 29, suspected to be the FSB, had been on the DNC’s network since at least summer 2015. APT 28, identified as Russia’s military intelligence agency GRU, had breached the Democrats only in April 2016, and probably tipped off the investigation.
