Ten Electoral College members have requested an intelligence briefing on Russia’s meddling in the U.S. presidential election, a week before the group is scheduled to formally certify the results.

The bipartisan group made their case to Director of National Intelligence James Clapper in an open letter Monday, arguing that the information is essential to their duties as electors who are tasked to “elect a president who is constitutionally qualified and fit to serve.”

Citing Alexander Hamilton’s writing in The Federalist Papers, the electors argue Russian interference in the election must factor into their decision. In Federalist #68, Hamilton charged the Electoral College with preventing a “desire in foreign powers to gain an improper ascendant in our councils.”

The Washington Post published details Friday of a CIA report that concluded Russia interfered with the U.S. presidential election to help Donald Trump win. The Trump camp responded by dismissing the report outright, despite calls from across the aisle for a more thorough investigation.

The letter continues:

The Electors require to know from the intelligence community whether there are ongoing investigations into ties between Donald Trump, his campaign or associates, and Russian government interference in the election, the scope of those investigations, how far those investigations may have reached, and who was involved in those investigations. We further require a briefing on all investigative findings, as these matters directly impact the core factors in our deliberations of whether Mr. Trump is fit to serve as President of the United States.

Senate Majority Leader Mitch McConnell (R-Ky.) said Monday it “defies belief” that Republican politicians would hesitate to review Russia’s intrusion. Former acting CIA director Mike Morrell called the Russian interference “the political equivalent of 9/11.”
