That whenever the laws of
the United States shall be <b>opposed or the execution thereof obstructed</b>,
in any state, by combinations too powerful to be suppressed by the ordinary
course of judicial proceedings, or by the powers vested in the marshals by this
act, the same being notified to the President of the United States, by an
associate justice or the district judge, it shall be lawful for the President
of the United States to call forth the militia of such state to <b>suppress</b>
such combinations, and to cause the laws to be duly executed. And if the
militia of a state, where such combinations may happen, <b>shall refuse</b>, or
be insufficient to suppress the same, it shall be lawful for the President, if
the legislature of the United States be not in session, to call forth and
employ such numbers of the militia of any other state or states most convenient
thereto, as may be necessary, and the use of militia, so to be called forth,
may be continued, if necessary, until the expiration of thirty days after the
commencement of the ensuing session.
