Impeachment trial: Senators to give speeches explaining their votes after closing arguments Monday

(CNN)The House impeachment managers and President Donald Trump's legal team will have a final chance Monday to make their pitch to any senators still on the fence about the verdict in the President's impeachment trial, even if the outcome is a forgone conclusion.

The impeachment managers and defense counsel are making their closing arguments for two hours each on Monday to summarize their case, starting with the House managers. The Senate is poised to acquit Trump when it takes a final vote on Wednesday at 4 p.m. ET. But there still is some uncertainty over the margin of the acquittal vote — and whether any senators cross party lines.

The end-game of the trial is set this week after the Senate voted last week to defeat a motion for subpoenaing witnesses and documents, which would have extended the proceedings. In that vote, which failed 49-51, two Republicans, Sens. Mitt Romney of Utah and Susan Collins of Maine, joined with Democrats.

A handful of senators in both parties have still not said whether they will vote to convict or acquit the President on the two articles of impeachment — abuse of power and obstruct of Congress — that the House passed in December.
