Jessie Liu, the Trump administration’s pick for third-in-command at the U.S. Justice Department, withdrew from consideration Thursday after reportedly facing opposition from members of the Senate Judiciary Committee over her past association with a legal group that opposed Justice Samuel Alito’s nomination to the Supreme Court.

Liu, the U.S. attorney in Washington, had been recommended for the role by Attorney General William Barr. The Justice Department did not immediately comment on why Liu had withdrawn her name from consideration.
