The following is a condensed version of the relevant facts. The subject has been well covered and the heritage article's many ...mis-statements have been debunked in other threads in this forum.
Flynn called the Russian ambassador on a tapped line. Not on Flynn's end, on the Russian end. Because they're the Russians. The calls were monitored/recorded. They discussed the sanctions in place on Russia as well as an upcoming UN Security Council resolution.
When the FBI interviewed Flynn, he was offered the chance to lawyer up. He declined. The FBI knew what Flynn had discussed. They asked if sanctions had been discussed. Flynn said no. In other words, he lied to the FBI. He admitted that in his plea bargain.
The Logan act was briefly discussed. That wasn't the reason for the interview. There was a counterintelligence concern because the Russians knew Flynn had lied and was vulnerable to blackmail. The interviewing agents didn't say they didn't think he lied. They said he didn't display the "tells" that many people display when they lie. A talent a high ranking intelligence official should have. Trump fired Flynn for lying to Pence.
The heritage article was murky at best and contained numerous omissions and misrepresented information.
"Dec. 22 — Flynn calls Kislyak and asks if Russia would delay or defeat an upcoming U.N. Security Council resolution vote that sought to condemn Israel’s building of settlements in the West Bank and East Jerusalem. The Obama administration agreed to allow the resolution to come up for a vote — angering Israeli Prime Minister Benjamin Netanyahu. (A day later, the U.N. resolution would pass, with Russia voting in favor and the U.S. abstaining from voting.)
Dec. 29 — With less than a month remaining in office, Obama announces “a number of actions in response to the Russian government’s aggressive harassment of U.S. officials and cyber operations aimed at the U.S. election in 2016.”
In a phone call with Kislyak, Flynn asks that Russia refrain from retaliating to the U.S. sanctions. Kislyak agrees that Russia would “moderate its response to those sanctions” as a result of his request, according to charges later filed against Flynn by the U.S. special counsel’s office. (Flynn’s conversation with the Russian ambassador would not become public until next year.)
Dec. 30 — Russian President Putin issues a statement saying that Russia would not retaliate for the U.S. sanctions. Putin says he hoped to improve relations with the United States “based on the policies of the Trump Administration.”
Trump tweets, “Great move on delay (by V. Putin) – I always knew he was very smart!”
2017
Jan. 12 — The Washington Post reports that Flynn and Kislyak spoke on Dec. 29, the day that the U.S. announced new sanctions on Russia in response to the cyberattacks during the 2016 presidential election. Incoming White House Press Secretary Sean Spicer denies that the call was about U.S. sanctions. “The call centered on the logistics of setting up a call with the president of Russia and the president-elect after he was sworn in,” Spicer said. “And they exchanged logistical information on how to initiate and schedule that call. That was it, plain and simple.”
Jan. 15 — Vice President-elect Mike Pence says Flynn and Kislyak did not discuss U.S. sanctions on Russia. “They did not discuss anything having to do with the United States’ decision to expel diplomats or impose censure against Russia,” Pence says.
Jan. 20 — Trump is inaugurated as the 45th president of the United States.
Jan. 22 — On the same day that Flynn is sworn in as the national security adviser, the Wall Street Journal reports that U.S. counterintelligence agents have investigated Flynn’s communications with Russian officials.
Jan. 24 — Two days after he takes office as national security adviser, Flynn is interviewed by FBI agents. He is asked about two conversations that he had with Kislyak, the Russian ambassador to the United States, in December 2016 when Flynn was still a private citizen and before Trump took office.
Flynn tells the FBI agents that he did not ask Kislyak, in a Dec. 29, 2016, conversation, for Russia to refrain from retaliating after the Obama administration announced sanctions that day against Russia for interfering in the 2016 elections. He also says that he did not ask Kislyak, in a Dec. 22, 2016, conversation for Russia to delay or defeat a U.N. Security Council resolution, approved Dec. 23, 2016, that would have condemned Israel’s building of settlements in the West Bank and East Jerusalem. Flynn would later plead guilty to lying to the FBI about both of those conversations with Kislyak.
Jan. 25 — The House Permanent Select Committee on Intelligence announces that it will investigate Russia’s efforts to influence the 2016 presidential election and “any intelligence regarding links between Russia and individuals associated with political campaigns.”
Jan. 26 — Acting Attorney General Sally Yates meets with White House counsel Donald McGahn in his office. She tells McGahn that high-ranking administration officials, including Vice President Pence, had made statements “about General Flynn’s conduct that we knew to be untrue.” She was referring to administration statements that Flynn did not discuss U.S. sanctions against Russia with the Russian ambassador. (Her meeting with McGahn would not be disclosed until Yates testified before Congress on May 8.)
Jan. 28 — Trump receives a congratulatory phone call from Putin.
Feb. 9 — The Washington Post reports that Flynn “privately discussed U.S. sanctions against Russia with that country’s ambassador to the United States during the month before President Trump took office, contrary to public assertions by Trump officials,” citing unnamed current and former officials.
Feb. 13 – Flynn resigns. He acknowledges that he misled Pence and others in the administration about his conversations with Kislyak, the Russian ambassador. “I inadvertently briefed the Vice President Elect and others with incomplete information regarding my phone calls with the Russian Ambassador,” Flynn says."
