331.FEDERAL AID FOR STATE GOVERNMENTS

     government, the President may, upon the request of its legislature
     or of its governor if the legislature cannot be convened, call 
     into Federal service such of the militia  of the other States,

332.USE OF MILITIA AND ARMED FORCES TO ENFORCE FEDERAL AUTHORITY

     combinations, or assemblages, or rebellion against the authority

     course of judicial proceedings, he may call into Federal
     service such of the militia of any State, and use such of the
     armed forces, as he considers necessary to enforce those laws

         of the United States within the State, that any part or
         class of its people is deprived of a right, privilege,
         immunity, or protection named in the Constitution and
         secured by law, and the constituted authorities of the
         State are unable, fail, or refuse to protect that right,
         privilege, immunity, or to give that protection; or       
      b) opposed or obstructs the execution of the laws of the
         United States or impedes the course of justice under

    Whenever the President considers it necessary to use the
    militia or the armed forces under this chapter, he shall,
    by proclamation, immediately order the insurgents to
