Executive Order on Imposing Certain Sanctions in the Event of Foreign Interference in a United States Election

FOREIGN POLICY

Issued on: September 12, 2018

What to watch for

Accordingly, I hereby order:

Section 1. (a) Not later than 45 days after the conclusion of a United States election, the Director of National Intelligence… [Now Flynn?!]

From and including: Tuesday, November 3, 2020

To and including: Thursday, December 17, 2020

Result: 45 days

It is 45 days from the start date to the end date, end date included.

So depending on when it's official "conclusion" was…

We're looking at movement to take place around or before 17th of Dec.

This isn't a guess, it's by Executive Order.
