Giuliani, Trump’s personal attorney at the time, put forward a computer whiz who presented a mathematical formula suggesting Biden’s support in certain states was unrealistic. Graham, a lawyer and chairman of the Senate Judiciary Committee, found the reasoning too abstract. He wanted hard evidence. “Give me some names,” Graham said at the Saturday meeting. “You need to put it in writing. You need to show me the evidence.”

Giuliani promised details by Monday — proof that scores of ballots had been cast in the names of dead people and people under 18, among other irregularities…

Graham and Lee, both of whom ultimately voted to certify the results, took the claims of election fraud seriously enough to get briefed on the details, involve their senior staff and call state officials throughout the country. But privately, Graham gave the arguments a withering assessment, according to the book, saying they were suitable for “third grade.”
