The world will be watching this week as 100 senators convene to consider convicting United States President Donald Trump, who was impeached on the grounds of abuse of power and obstructing Congress.
Several questions still remain. Will witnesses be allowed to testify? Will the president be acquitted? And where will Trump be during all of this, anyway?
We answer some of the questions surrounding the upcoming Senate impeachment trial.
The trial formally began on Thursday, but the Senate will sit as a court of impeachment for Trump’s trial on Tuesday at 1 p.m. ET.
Historic rules determined by the Senate say the trial will run six days per week — Monday to Saturday — until it is finished.
The duration of the trial, though, depends on a number of factors, including whether witnesses are called to testify.
The parameters of the trial — including speaking time and the possibility of witnesses — will be laid out Tuesday afternoon in a resolution from Senate Majority Leader Mitch McConnell that will kick off the proceedings.
It is still unclear if witnesses will be called to testify at the trial.
For weeks, Democrats have been pushing to hear from witnesses who did not appear before the House committees spearheading the impeachment inquiry.
They are seeking testimony from White House acting chief of staff Mick Mulvaney, his senior adviser Robert Blair, former national security adviser John Bolton and Office of Management and Budget official Michael Duffey.
McConnell, however, has lambasted the Democrats over their calls for witnesses, calling it a “fishing expedition.”
“If the existing case is so strong, there’s no need for the judge and jury to reopen the investigation,” McConnell told reporters on Tuesday.
