Despite the whirlwind of revelations over the past year, as well as efforts by President Trump and his defenders in Congress to distract and confuse and brand the investigation a “witch hunt,” the Trump-Russia story remains, at its core, a relatively simple one.

On Jan. 6, 2017, the U.S. intelligence community released its report on Russian interference in the 2016 election, effectively concluding that there were two campaigns to elect Donald Trump: one run out of Trump Tower and one run out of the Kremlin.

Since then, we’ve learned that there were no bright lines between the two campaigns. They had the same goal, the same strategy and were in constant contact during the campaign and transition.
