The dueling filings previewed arguments both sides intend to make once Trump's impeachment trial begins in earnest Tuesday in the Senate. New information from Lev Parnas, an indicted associate of Trump lawyer Rudy Giuliani, is being incorporated in the House case. White House attorneys and Trump's outside legal team have been debating just how political Monday's legal brief laying out the contours of Trump's defense should be. People close to the Trump legal team said Cipollone would deliver the president’s opening argument before the Senate and that Sekulow would follow. Starr and Dershowitz would have “discrete functions” on the legal team, according to those close to the legal team, who were not authorized to discuss the strategy by name and spoke on condition of anonymity.
