as a result of the events of 1910, at the start of the 64th congress in 1915, the committee assignments were made by each party and then formally approved by the whole house. each party controlled the committee ranking of its members, but usually this followed the order of seniority of members in terms of service on the committee. it became customary for members of a committee, in the previous congress, to be re-appointed at the start of the next.
