Impeachment proceedings may be commenced by a member of the House of Representatives on her or his own initiative, either by presenting a list of the charges under oath or by asking for referral to the appropriate committee. The impeachment process may be initiated by non-members. For example, when the Judicial Conference of the United States suggests a federal judge be impeached, a charge of actions constituting grounds for impeachment may come from a special prosecutor, the President, or state or territorial legislature, grand jury, or by petition.

Is it true that can the house of representatives impeach a federal judge?
