Each senator was given ten minutes of speaking time to talk on the Senate floor.
Senators are set to explain their positions on impeachment ahead of a final vote Wednesday on whether acquit President Donald Trump or remove him from office.
After House impeachment managers and Trump's defense team finished their closing arguments Monday, senators were given time to speak on the trial. Those speeches are expected to continue Tuesday.
Only a handful of senators remain publicly uncommitted on their final impeachment votes, and some might use the speeches as an opportunity to explain their position to their constituents.
The speeches also come the same day Trump will give his State of the Union address.
