Loretta Lynch was sworn in Monday as the 83rd U.S. attorney general, becoming the first African-American woman to serve as the nation's top law enforcement official.
She said her confirmation as attorney general showed that "we can do anything" and pledged to deal with cyberattacks and other threats facing the country.
Vice President Joe Biden administered the oath of office to Lynch at a Justice Department ceremony. Lynch replaces Eric Holder, who left the job Friday after six years as attorney general.
The 55-year-old Lynch was confirmed by the Senate on Thursday following a months-long delay in which her nomination became caught up in a dispute over human trafficking legislation.
