The Senate narrowly approved a $1.4 trillion tax overhaul early Saturday morning following a day of procedural delays and frustration.

The legislation, which would cut the top corporate tax rate to 20 percent and lower taxes for most individuals, narrowly passed in a vote of 51-49. Tennessee Republican Bob Corker was the only Republican to vote against the legislation, joining every Democrat and both independents in opposing the sweeping overhaul of the nation's tax laws.
