The Senate impeachment trial of President Donald Trump enters its third day Thursday as Democratic leaders from the House of Representatives continue to make their case to remove the president from office.
Supervised by Supreme Court Judge John Roberts, the trial will continue in the Senate at 10:00 PT / 1 p.m. ET and is set to run six days a week, including Saturdays, for potentially three to five weeks. After the rules were signposted during a 13-hour Day 1 session, Thursday continues the 24-hour period, which is spread over three days assigned to the impeachment chiefs to speak out against the president. The president's lawyers will then have a similar 24-hour window spread over three days to create a defense.
It is about whether Trump should be removed from his work for his conduct in connection with Ukraine. It includes a phone call in July where 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 to a Ukrainian gas company, in exchange for the US military  In the December vote, the House adopted two articles on detention that accused Trump of abusing power and impeding Congress. Both votes largely went over the party lines in the Democratic-controlled House. The votes of 67 senators in the Republican-controlled Senate are required to remove the president from office.

Who else has been impeached?
Trump joins Andrew Johnson and Bill Clinton as the third president accused by the House since the constitution was passed in 1788.
Richard Nixon resigned before the House had a chance to hire him for his role in the Watergate scandal. Both Johnson and Clinton were acquitted by the Senate in their respective impeachment attempts.
What does Trump have to say?
In a six-page letter to House Speaker Nancy Pelosi in December before voting in the House, Trump blasted the lawsuit, saying that "those accused in the Salem Witch trials had gotten more litigation.
" It's time for you and the very partisan Democrats in Congress to immediately cease this impeachment fantasy and return to the work of the American people, "the president wrote." While I do not expect you to do so, I am writing this letter to you for the purpose of history and to put my thoughts on a permanent and indelible record. "
Where is Trump right now?
