>> President Donald Trump was set off by the defense mustered by his legal team at the start of his Senate impeachment trial, raging at key admissions and a presentation that appeared to drive away a key Republican vote. >> Trump, viewing the proceedings from his new home at Mar-a-Lago, was aghast that one of his lawyers, Bruce Castor, acknowledged the potency of the opening argument put forward by House Democratic impeachment managers, ABC News reported. >> Castor even acknowledged that his team changed course after viewing the Democrats' presentation, which featured dramatic video of Trump supporters storming the Capitol and taunting police officers with obscenities as they bashed in doors and windows. >> ‘I’ll be quite frank with you, we changed what we were going to do on account that we thought that the House managers’ presentation was well done,’ Castor admitted. ‘And I wanted you to know that we have responses to those things.’ >> During three-and-half hours of debate on the Senate floor Tuesday, the defense and prosecution had the chance to argue whether holding an impeachment trial of a former official is in line with the Constitution. >> Several Republicans, however, are ridiculing Trump's defense team for missing the point of their outlined argument against the constitutionality of the timing of the proceedings. >> 'I thought the President's lawyer – the first lawyer just rambled on and on and on and didn't really address the constitutional argument,' Texas Senator John Cornyn told reporters outside the chamber following his vote against moving forward.
