Prosecutors have questioned witnesses about Rudy Giuliani's alcohol consumption while advising Trump, including on election night.
Investigators are interested in whether Trump knew Giuliani was intoxicated when following his advice to challenge 2020 election results.
Giuliani's drinking habits could weaken Trump's possible "advice of counsel" defense in the federal interference case.
