The Senate will begin hearing the House impeachment managers' case against President Donald Trump this week on charges of abuse of power and obstruction of Congress.
In a trial set to begin Tuesday at 1 p.m. EST, the seven Democrats will argue that the president committed "high crimes and misdemeanors" by withholding military aid to pressure Ukraine to announce politically advantageous investigations, and by blocking a congressional investigation.
Republicans are largely standing by Trump, arguing that House Democrats rushed the investigation and failed to make their case. Senate Majority Leader Mitch McConnell has said he's not an impartial juror and that he is working in "total coordination" with Trump's defense lawyers.
WHERE TO WATCH
The cable news networks, CNN, Fox News and MSNBC, are likely to show significant portions of the trial. C-SPAN 2, which covers Senate floor proceedings, will broadcast it on cable and online.
Starting Tuesday, the trial is expected to run every day but Sunday, beginning at 1 p.m., under Senate rules adopted in 1986.
McConnell will offer a resolution supplementing the rules to track the procedures used in President Bill Clinton's 1999 trial by setting time limits for each side's opening arguments followed by questions from senators.
After that, senators would decide whether to call witnesses and seek additional documents.
Senate Minority Leader Chuck Schumer wants to offer amendments calling for more documents and testimony from four witnesses. Debate over the rules will take place behind closed doors, barring the unlikely success of a Democratic bid to keep deliberations open. The roll call votes on the resolution and amendments will be held in public.
