Under the supervision of Supreme Court Chief Justice John Roberts, the trial will run six days a week, including Saturday, possibly for three to five weeks. After the rules were broken down on Tuesday into a 1-hour 1-hour session, Friday marked the last day on which House Democrats were allowed to declare their case against the president. Their 24 hours culminated in conclusive arguments by Congressman Adam Schiff, who made a passionate plea for a fair trial.
The lawyers of the president now have a similar 24-hour period spread over three days to set up a defense. The former reality TV star does not seem excited about the Saturday start of his defense, tweet that it is the " Death Valley in TV "
what matters in the process is whether Trump must be removed from office for his conduct in dealing with Ukraine. That includes a phone call in July in which he appears to have asked the President of Ukraine to investigate former US Vice President Joe Biden, currently a democratic presidential candidate, and his son Hunter Biden's ties with a Ukrainian gas company in exchange for the US army
In the December vote, the House adopted two accusation articles accusing Trump of abusing power and hampering Congress. Both votes were largely cross-party in the Democratically-controlled House. The votes of 67 senators in the senate controlled by the republicans are required to put the president out of office.

How can I watch?
Different news networks and outlets will stream the events of the day. A number of broadcasters, including PBS and Fox News, MSNBC, CNN and C-SPAN cable news channels, have refused to offer live broadcasts prior to regular programming. (Disclosure: CNET is a division of CBS Interactive, owned by ViacomCBS.)
Local broadcasters CBS, ABC and NBC have also banned regular programming for the first few days of the trial.

What time does it start?
The Senate trial on Saturday begins earlier than normal at 7 pm PT / 10 pm ET. After a Sunday break, it starts again on Monday. During the four days last week it started later in the day, at 10 a.m. PT / 1 p.m. ET, so expect the same schedule next week.
Who else has been dropped off?
Trump joins Andrew Johnson and Bill Clinton as the third president to be deposed by the House since the constitution was adopted in 1788.
Richard Nixon resigned before the House had the chance to accuse him of his role in the Watergate scandal. Both Johnson and Clinton were acquitted by the Senate in their respective deposition sentences.
What does Trump have to say?
In a six-page letter to House Speaker Nancy Pelosi in December prior to the House vote, Trump destroyed the procedure and said, "more appropriate trial was offered to those accused in the Salem Witch Trials. "
"It is time for you and the very partisan Democrats in Congress to immediately stop this accusation fantasy and go back to work for the American people," wrote the president. "Although I don't expect you to do that, I am writing this letter to you for the purpose of history and to place my thoughts on a permanent and indelible report."
