Trump nears delegate threshold after Washington win

Washington

DONALD Trump won Tuesday's Republican presidential primary in Washington state, according to the Associated Press (AP), putting the party's presumptive nominee on the cusp of crossing the delegate threshold required to formally secure his party's nomination.

The only Republican candidate remaining in the field, Mr Trump has begun running a general-election campaign - criticising likely Democratic rival Hillary Clinton, narrowing his search for a running mate, and putting together a fundraising team.
