Questions of precedent come forth as the U.S. House of Representatives conducts an impeachment investigation into President Donald Trump.

One concern among supporters of impeachment is that the U.S. Senate could halt further action if the House votes in favor of impeachment. Aurora University Assistant Professor Matthew Dabros says chamber rules require the Senate to take action, but members could vote to dismiss the charges.

Editor's note: Many performances of Handel's most famous oratorio invite audience participation. These are called Sing-Along Messiahs, Scratch Messiahs, People's Messiahs, and Do-It-Yourself-Messiahs. For this article about performances in which unrehearsed attendees serve as the chorus, we'll refer to each of them as "Messiah."

George Frideric Handel's oratorio "Messiah" shows up in concerts regularly this time of year.  But some performances call for the audience to join in.
