Justin A. Amash is an American lawyer and politician who served as the U.S. representative for Michigan's 3rd congressional district from 2011 to 2021. He was the second Palestinian-American member of Congress. Originally a Republican, Amash left the GOP and became an independent on July 4, 2019. In April 2020, he joined the Libertarian Party, leaving Congress in January 2021 as the only Libertarian to serve in Congress.

The 2020 Libertarian Party presidential primaries and caucuses were a series of electoral contests to indicate non-binding preferences for the Libertarian Party's presidential candidate in the 2020 United States presidential election. These differ from the Republican or Democratic presidential primaries and caucuses in that they do not appoint delegates to represent a candidate at the party's convention to select the party's presidential nominee.
