Alina Habba's role as acting U.S. Attorney faces a test after an attorney in a drug and weapons case filed a motion challenging her authority to prosecute it.

President Trump's bid to keep Alina Habba in charge of the U.S. attorney's office in N.J. faces a new test after a defendant filed a motion challenging her authority.

Federal judges appointed Desiree Leigh Grace to replace Habba before U.S. Attorney General Pam Bondi fired her.
