'Still wearing diapers?' Donald Trump tells protester as clashes erupt outside rally
Democratic frontrunner Hillary Clinton and presumptive Republican nominee Donald Trump have each won primaries in Washington state.
Mr Trump's win helps him inch closer to clinching his party's nomination for president. He is within 41 delegates of the number needed to become the Republican nominee.
Mrs Clinton's win might give her some momentum, but it will not get her any delegates. There were no delegates at stake in the Democratic primary. Washington Democrats have already awarded their delegates based on party caucuses.
Vermont Senator Bernie Sanders won Washington's caucuses in March, getting 74 delegates. Mrs Clinton got 27.
Republicans in Washington will allocate all 44 delegates to their national convention based on the primary results.
Mr Trump won at least 27 delegates, with 17 still left to be allocated. The billionaire businessman has 1,196 delegates. It takes 1,237 delegates to win the GOP nomination.
There are no more Republican contests until June 7, when the last five states vote. With a total of 303 delegates at stake in California, Montana, New Jersey, New Mexico and South Dakota, Mr Trump should easily clinch the nomination that day.
He is the only remaining candidate in the Republican contest. But his former opponents, Ohio Governor John Kasich and Texas Senator Ted Cruz, were still on the ballot because they suspended their campaigns after the ballots were printed. Ben Carson was also on the ballot because he never submitted the paperwork to have his name removed.
Mr Sanders trails Mrs Clinton in the delegate count and he is running out of contests in his bid to catch up.
Mrs Clinton is just 78 delegates short of clinching the Democratic nomination for president. She is on track to do so in early June, even if she loses all the remaining contests.
She has 1,768 pledged delegates won in primaries and caucuses. Mr Sanders has 1,497.
Her lead is even bigger when superdelegate endorsements are included. These are the party leaders and elected officials who can support the candidate of their choice.
Overall, Mrs Clinton has 2,305 delegates and Mr Sanders has 1,539. It takes 2,383 delegates to win the Democratic nomination.
Meanwhile protests outside a rally Mr Trump was holding in New Mexico turned violent as demonstrators threw burning T-shirts, plastic bottles and other items at police officers, and knocked down barricades.
Police responded by firing pepper spray and smoke grenades into the crowd outside the Albuquerque Convention Centre.
During the rally, Mr Trump was interrupted repeatedly by protesters, who shouted, held up banners and resisted removal by security officers.
The banners included the messages "Trump is Fascist" and "We've heard enough".
At one point, a female protester was physically dragged from the stands by security. Other protesters scuffled with security as they resisted removal from the convention centre, which was packed with thousands of cheering Trump supporters.
Mr Trump responded by instructing security to remove the protesters and mocking their actions by telling them to "go home to mommy".
He responded to one demonstrator by asking: "How old is this kid?" Then he provided his own answer: "Still wearing diapers."
The altercations left a glass door at the entrance of the convention centre smashed.
It was Mr Trump's first stop in New Mexico, the nation's most Hispanic state. Governor Susana Martinez, head of the Republican Governors Association and the nation's only Latina governor, has harshly criticised his remarks on immigrants and attacked his proposal to build a wall along the US-Mexico border.
The governor did not attend the rally and has yet to make an endorsement.
