the whole thing stinks to high heaven
1) in the winter of 2014 after three decades in the military, Retired Lt. Gen. Michael Flynn was fired as head of the Defense Intelligence Agency (DIA).
One former official told The Washington Post that Flynn attempted to push DIA analyses and operators into the field and other high-intensity operations. This ran counter to how the DIA saw itself, leading many to believe that Flynn's vision for the agency was disruptive.
2) in 2015 Flynn delivered a paid speech in Moscow and also dined with Putin.
On the trip, Flynn attended a 10th anniversary gala celebration for RT, the pro-Russia news outlet owned by the Russian government. At the gala, Flynn appeared on a panel and then sat next to Putin during dinner. Flynn retired from the military prior to the trip, but the Democratic letter, which was signed by top Democrats on the House Oversight, Armed Services, Judiciary, Homeland Security, Intelligence, and Foreign Affairs committees , notes that he may still have been covered by the Emoluments Clause.
3) According to Business Insider, Tillerson initially met Putin in 1999 on the Sakhalin island in Russia's Far East, when Exxon struck a deal with Russian state-owned oil giant Rosneft.
In 2011, Exxon signed another deal with Rosneft for a lucrative $3.2 billion oil deal that would give Exxon permission to develop offshore oil fields in the Russian Arctic in exchange for Rosneft getting stakes in a number of Exxon's US-based projects.
Rosneft and Exxon were enthusiastic about the deal and expanded it in 2013. But it was canceled one year later, when the US imposed sanctions on Russia over its annexation of Crimea and invasion of Eastern Ukraine. Tillerson sharply condemned the sanctions, saying they caused "broad collateral damage."
In 2012, Putin presented Tillerson with a Russian medal at an award ceremony of heads and employees of energy companies at the St. Petersburg economic forum in St. Petersburg, Russia.
Critics have expressed concern over Tillerson's nomination because of potential conflicts of interest. One of the first issues on Tillerson's agenda, for example, may be weighing whether to lift sanctions on Russia. Tillerson currently holds $151 million in Exxon stock, and the value of that stock would increase if sanctions were lifted.
Putin even personally awarded Tillerson with Russia's Order of Friendship medal in 2013, the highest honor bestowed on foreign citizens. It is given to foreigners whom the Russian government believes have helped Russia and its people.
4) Trump nominated Flynn and Tillerson to key posts of his administration
