CBS News reports:
Senators on Thursday prepared for a second day of questions for both the Democratic House managers and the defense team in President Donald Trump’s impeachment trial. Senators asked more than 90 questions Wednesday on everything from executive power to the ability to call witnesses — an issue that has lawmakers sharply divided.
Ahead of the vote on Friday afternoon on whether to call witnesses at President Donald Trump’s impeachment trial, GOP Senate leaders believe they will have just enough votes to block additional testimony and documents. In order for witness testimony to be approved, four Republicans in the Senate would need to vote alongside all Democrats.
