Republicans are set to begin reading aloud the entire U.S. Constitution on the floor of the House for the first time in congressional history.

In two other instances the Constitution has been inserted into the congressional record, once in 1882 and once in 1915, but never read aloud, a representative of the House Office of the Historian told The Hill this morning.

Prior to the reading, Republicans and some Democrats lined up to voice their support for the unusual action.
