Fresh from interviewing former White House press secretary Sean Spicer over what he was doing on the fifth floor of Trump Tower on election night, Democrats now want to interview former Republican National Committee Chairman Reince Priebus.

Spicer’s presence that night has caused some unease among Republicans because the expiration of a 35-year-old settlement, or consent decree, barring the RNC from engaging in ballot security operations may depend on it. The fifth floor, POLITICO has reported, was the nerve center of then-candidate Donald Trump’s poll-watching operations.

Spicer, at the time, was the RNC’s communications director and chief strategist.
