Who was the Vice President under Donald Trump?

The Vice President under Donald Trump was Mike Pence. He served in this role from January 20, 2017, until January 20, 2021. As Vice President, Pence was involved in several key initiatives and policies during the Trump administration, including efforts in foreign policy, health care reform, and economic development. His position also involved acting as a tie-breaking vote in the Senate and assuming the presidency in the event that Trump was unable to fulfill his duties.

The other individuals mentioned were not vice presidents during Trump's term. Joe Biden was the Vice President under Barack Obama, Paul Ryan served as the Speaker of the House during Trump's presidency, and Newt Gingrich was the Speaker of the House in the late 1990s. Their roles and timelines do not align with the vice presidency under Trump, confirming Mike Pence as the correct answer.
