Uncertainty gripped the Library of Congress on Monday as the White House moved to assert more control over the legislative branch agency, naming Deputy Attorney General Todd Blanche as its acting head.

President Donald Trump's onetime defense attorney has been appointed acting librarian of Congress. Deputy Attorney General Todd Blanche replaces longtime librarian Carla Hayden, whom the White House fired last week amid criticism from some conservatives that she was advancing a “woke” agenda.

Deputy Attorney General Todd Blanche will also serve temporarily as librarian of Congress after the dismissal of Carla Hayden.
