If the defendant appears, the defendant may object in writing to the sufficiency of the articles of impeachment or may answer the same in writing or by oral plea. Such plea must be entered upon the journal. A plea of not guilty puts in issue every material allegation of the articles of impeachment and the specifications thereunder.
