The group of electors, which includes the daughter of House Democratic Leader Nancy Pelosi (Calif.), wrote an open letter to Director of National Intelligence James Clapper asking for the information ahead of their Dec. 19 meeting to formally vote for the next president.

“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,” the letter read. “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.”

Nine Democrats and one Republican signed the letter. The Republican, Christopher Suprun, has said that he won't vote for Trump when the Electoral College meets.

The Monday letter comes three days after The Washington Post reported that the CIA believes Russian hackers obtained and released, via WikiLeaks, Democratic National Committee emails to sway the election for Trump.
