Acting White House Chief of Staff Mick Mulvaney withdrew an effort to join a lawsuit asking a federal judge to decide which authority to follow: Congress or President Donald Trump.
Charles Kupperman, an aide to former National Security Advisor John Bolton who left the White House around the same time Bolton did, filed the suit after being subpoenaed by House Democrats to testify in the impeachment probe, expressing confusion as to whether he should obey Congress or listen to Trump’s White House, which guided him not to comply with the subpoena.
