It's the quote that may end up making Donald Trump only the third U.S. president to be formally impeached by the House of Representatives. It's now topped a list of the ten most notable quotes of 2019.

The Yale Book of Quotations has been updated to include a list by Yale Law School librarian Fred Shapiro of the top quotes of the year.

They come from people at all levels of power on the national and international stage; from an actress who has a new way to describe her relationship status; from a 16-year-old climate activist who stared down world leaders and told them they are failing; and from the highest-grossing movie of all-time.

At No. 1 on the list is a quote from the phone call between Trump and Ukrainian President Volodymr Zelensky on July 25 in which Trump said, “I would like you to do us a favor, though.” Concerns over that call ultimately led to a more than two-month investigation by the House. Democrats say Trump abused his power in withholding $400 million in military aid to Ukraine in exchange for the requested favor to investigate Democrats.

With articles of impeachment expected to be unveiled Tuesday, Trump could be formally impeached before Christmas.
