 Marshall was not offended by Wilson 's lack of interest in his ideas , and considered his primary constitutional duty to be in the Senate . He viewed the vice presidential office as being in the legislative branch , not the executive . While he presided in the Senate , emotions sometimes ran high , including during a debate on the Mexican border crisis in 1916 . During that debate Marshall threatened to expel certain senators from the chamber for their raucous behavior , but did not carry through on the threat . On several occasions , he ordered the Senate gallery cleared . He voted eight times to break tie votes .
