House Intelligence Chairman Adam Schiff (D-Calif.), one of the House impeachment managers in the Senate trial, remarked that the question of witnesses might have to be resolved by Supreme Court Chief Justice John Roberts, who will preside over the process.
“It would certainly be fair for the president and his team to be able to call witnesses that can provide material information on the charges. It would not be appropriate for the president to seek to call witnesses” to try and criticize former Vice President Joe Biden and his son, Hunter ahead of the 2020 election, Schiff suggested to CBS News on Monday night.
