The Senate reconvenes today for the Republican-led impeachment trial of President Donald Trump, who last year became the third president in history to be impeached by the House of Representatives. Seven Democrats have been named as managers to prosecute the House’s case, including Intelligence Committee chairman Rep. Adam Schiff of California and Judiciary Committee chairman Rep. Jerrold Nadler of New York. White House counsel Pat Cipollone and Trump’s personal lawyer, Jay Sekulow, are expected to take the lead in arguing the president’s case. On Friday, Trump added two members to his legal team: Alan Dershowitz and Ken Starr. Both nationally known attorneys and regular pundits on Fox News, Dershowitz has a background in constitutional law, while Starr is famous for having led the investigation into former President Bill Clinton. On Thursday, after the House managers formally delivered the two articles of impeachment to the Senate, Chief Justice John Roberts was sworn in to preside over the trial, before swearing in the senators in attendance.
