A House committee voted Wednesday to grant immunity to Monica Goodling, a key aide to Attorney General Alberto Gonzales during the firings of eight U.S. Attorneys. She had refused to testify, invoking her Fifth Amendment rights against self-incrimination.

The 32-6 vote by the House Judiciary Committee surpassed the two-thirds majority required to grant a witness immunity from prosecution. A separate vote to authorize a subpoena for Goodling passed by voice vote.
