The Republican-controlled US House of Representatives passed a landmark tax overhaul Tuesday, bringing it one step closer to adoption in what is set to deliver a political triumph for President Donald Trump.

Republicans received zero Democratic support as they passed the contentious $1.5-trillion package of tax cuts for businesses and individuals, the most comprehensive revamp of the nation's tax code in three decades.

The bill now heads to the Senate, where the margin of support appears to be tighter, for a vote that Majority Leader Mitch McConnell said would likely occur during Tuesday night's session.
