House impeachment managers and President Trump’s defense team delivered their closing arguments on Monday with an eye toward history, but with little hope of changing any senator’s mind.

The arguments came on the same day that caucusgoers in Iowa will gather to narrow the Democratic field, and lawyers on both sides tried to appeal to 2020 voters in their arguments. The formal vote on whether to acquit Mr. Trump will take place on Wednesday. Here are the key takeaways from the closing arguments.

With a focus on history, House managers make their final arguments.

Invoking former President Abraham Lincoln, and the founding fathers Alexander Hamilton and James Madison, House impeachment managers delivered closing arguments written for the history books, and in some cases attempted to shame senators for not removing Mr. Trump from office.

“But all is not lost, even at this late hour. The Senate can still do the right thing,” one of the House impeachment managers, Representative Hakeem Jeffries, Democrat of New York, said on Monday. “America is watching. The world is watching. The eyes of history are watching. The Senate can still do the right thing.”
