(FOX NEWS) -- A marathon, 12-hour first day in the Senate impeachment trial against President Trump erupted into a shouting match well after midnight Wednesday morning, as Trump's legal team unloaded on Democratic impeachment manager Rep. Jerry Nadler, D-N.Y. -- in an exchange that prompted a bleary-eyed Chief Justice John Roberts to sternly admonish both sides for misconduct in the chamber.
Nadler began the historic spat by speaking in support of the eighth amendment of the day, which was proposed by Senate Minority Leader Chuck Schumer, D-N.Y., just as the clock struck midnight. The proposal would have amended the trial rules offered by Senate Majority Leader Mitch McConnell, R-Ky., to immediately subpoena former National Security Advisor John Bolton.

McConnell's rules, which were eventually adopted in a 53-47 party-line vote at 1:40 a.m. ET Wednesday and largely mirror those from the Bill Clinton impeachment trial in 1999, permit new witnesses and documents to be considered only later on in the proceedings, after opening arguments are made.
