This Abridge News topic aggregates four unique arguments on different sides of the debate. Here are the quick facts to get you started:

THE QUICK FACTS

• On Wednesday, Attorney Alan Dershowitz, a member of President Trump's legal defense team, offered a controversial argument during Senate impeachment proceedings. 
• In response to a question about whether it mattered if Trump engaged in a quid pro quo, Dershowitz said motive was what mattered and if an act was in the public interest, it was not impeachable.
• "Every public official that I know believes that his election is in the public interest. And if a president does something which he believes will help him get elected in the public interest, that cannot be the kind of quid pro quo that results in impeachment."
• Dershowitz said a quid pro quo that involved an illegal act, or was done for personal financial gain, would be impeachable.
• The argument quickly drew criticism from democratic lawmakers, who say the reasoning sets a dangerous precedent when it comes to abuse of power.
