Three recently reported events each point to a tightening of the investigative net around Trump campaign's possible involvement with Russia and further financial ties to oligarch money.
The first event is the investigation's cooperation with the the IRS Criminal Investigation Unit as reported by the Daily Beast. In the article, Betsy Woodruff quotes Martin Sheil, a retired IRS Criminal Investigator:
And he said Mueller and Weissmann are known admirers of those agents’ work.
“They view them with the highest regard,” Sheil said. “IRS special agents are the very best in the business of conducting financial investigations. They will quickly tell you that it took an accountant to nab Al Capone, and it’s true.”
The thought of IRS investigators and Mueller's forensic accountants toiling away must be causing some anxiety in the Trump administration.
The second event is the cooperation of Robert Mueller's team and New York Attorney General Eric Schneider, as reported by Josh Dowsy of Politico. Per Politico, the teams are sharing evidence on the financial affairs and lobbying efforts of Paul Manafort.
Involvement of AG Schneider has the possibility of creating pressure on Manafort that President Trump cannot mitigate. Article II, Section 2 of the Constitution gives the president the "Power to Grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment." This means State criminal prosecutions are not affected.
The third event is the surfacing of a draft version of Trump's letter firing FBI Director Comey. This letter reported by the New York Times, coauthored by Stephen Miller, White House Aide, was vetoed by White House counsel Don McGahn as "its angry, meandering tone was problematic." Per the New York Times, Miller was not involved in the letter's content.
The fact that the firing of Comey is under such careful inspection implies that Trump's jeopardy for obstruction of justice accusations may be rising.
Another difficult week for the President and his associates.
