The Washington Post has posted a newly compiled timeline of Trump campaign officials' known contacts with Russians throughout the 2016 election season:
Despite denials from the campaign and the White House, it is now clear that members of the Trump campaign interacted with Russians at least 31 times throughout the campaign. (There are at least 19 known meetings.) Knowledge of these communications went to the highest levels of Donald Trump’s operation — both Corey Lewandowski and Paul Manafort, two of the campaign’s three managers, were aware of it.
Since the information about members of the Trump campaign’s contacts with Russians has come out in dribs and drabs, as a public service, we compiled a comprehensive timeline of what we now know from media reports and court documents detailing which members of the campaign met with Russians during the campaign as well as internal discussions about those meetings. We will update this timeline as necessary.
See the full timeline here, and compare what we know now with what we heard from Trump about Putin on the campaign trail; what the team was saying when it denied contact; and what similar messaging was emerging from Trump and Russia in mid-2016.
The New Yorker's Ryan Lizza argues the slow drip of information benefits the Trump campaign both by disguising the full magnitude of the Russia investigation and softening its potential blow:
The Russia investigation is occurring mostly behind closed doors in Congress and by the special counsel, somewhat muting the impact of revelations that regularly leak out. Will this slow and confusing release of damaging information soften the blow to Trump? It’s too soon to tell, of course, but what he and his team are banking on is that, while a year ago the public might not have tolerated the full truth about his campaign’s links to Russia, the scandal goes down a lot easier when the details are delivered in small bites.
