“CIA briefers faced a difficult situation after the 2000 election, when the country didn't know for some time whether Republican George W Bush or Democrat Al Gore had won.
Bush had received a four-hour CIA briefing in September before the election at his ranch in Crawford, Texas, but he had never seen the President's Daily Brief, which Gore saw daily as vice president.
As their lengthy ballot recount dragged into December, President Bill Clinton authorized intelligence officials to share the so-called PDB with Bush, too."
From what I've read the transition from Clinton to Bush was shortened due to the issues of the recount in Florida. I don't think any fair-minded individual would argue that the circumstances are similar for the 2020 election.
