In the US Constitution, impeachment and conviction are not the same things. To impeach is to bring charges against a high-office holder.

The House of Representatives can start the impeachment process with simple majority vote to bring charges against the president. In the impeachment trials The House of Representatives acts like a prosecutor. The Senate sits as a jury. Two-thirds of the Senators must find the sitting president guilty for him to be removed; per the US Constitution:

The Senate shall have the sole power to try all impeachments. When sitting for that purpose, they shall be on oath or affirmation. When the President of the United States is tried, the Chief Justice shall preside: And no person shall be convicted without the concurrence of two thirds of the members present.

A separate question asks if Trump will be impeached given that the Democrats retake the house. This has now occured, so that question now asks whether Trump will be impeached.

This questions asks: IF Trump is impeached, will the Senate remove him from office?

Question resolve positive if Trump is removed due to Senate vote after impeachment by the house. Resolves negative if Trump is acquitted by the Senate, or otherwise leaves office prior to the vote. Resolves ambiguous if Trump is not impeached by Jan 18, 2021. For maximal suspense, question will remain open until the beginning of the Senate vote, closing retroactively one hour prior to that first vote.
