Melville Fuller,
In re Chapman (166 U.S. 661) — Opinion of the Court
“ Under the constitution, the senate of the United States has the power to try impeachments; to judge of the elections, returns, and qualifications of its own members; to determine the rules of its proceedings; punish its members for disorderly behavior; and, with the concurrence of two-thirds, expel a member; and it necessarily possesses the inherent power of self-protection. ”
