The dismissal of Librarian of Congress Carla Hayden has triggered a group of Democratic lawmakers to request an investigation of potential improper communication between the Library of Congress and the executive branch.

Carla Hayden, the first African American and woman to lead the Library of Congress, was dismissed without explanation.

Carla Hayden has been the Librarian of Congress since 2016. She was the first woman and African American to hold the position.
