U.S. Senator Bernie Sanders has endorsed former rival Hillary Clinton as the Democratic nominee for the US presidential election.
"Secretary Clinton has won the Democratic nominating process," Sanders said to cheers in Portsmouth, New Hampshire.
"And I intend to do everything I can to make certain she will be the next president of the United States.
"Addressing the very serious crises that we face... there is no doubt in my mind that as we head into November, Hillary Clinton is by far and away the best candidate to do that."

The US State Department has reopened an internal investigation of possible mishandling of classified information by Hillary Clinton and senior aides.
The investigation is restarting following the decision by the Justice Department not to pursue a criminal investigation, spokesman John Kirby said.
The State Department suspended its review in April to avoid interfering with the FBI's inquiry.
Mr Kirby set no deadline for the investigation's completion.
On Tuesday, FBI Director James Comey said Clinton had been "careless" when when handling her emails.
The Democratic presidential contender has been the subject of a long-running controversy over her use of private email while she was Secretary of State until early 2013.
The United States could have completed the invasion of Iraq without the help of the UK, a former US Army colonel has said.
Colonel Peter Mansoor, executive officer to General David Petraeus who led the 2007 American military "surge" in Iraq made the comments while speaking to Good Morning Britain.
He added: "More importantly, it might have given the Bush administration some pause", and added that the "special relationship" between the US and the UK was not about "linking arms".
He called the Iraq War "one of the largest, strategic mistakes in American history", saying he "applauded" the British government for launching the inquiry.
The former UK ambassador to the UN in 2003 has said that he believed Tony Blair felt "pushed" into going to war by the Americans.
I felt that at the time, the British felt it at the time, I think the prime minister felt it at the time, that the Americans pushed us into going into military action too early.
Speaking to the BBC Sir Jeremy added that the former prime minister had wanted a UN resolution backing military intervention in Iraq, but that senior US officials thought it was a "waste of time".
The US State Department has said it will not respond to the Chilcot report's findings, as its focus is on tackling the issues present in the Middle East today.
We are not interested in re-litigating the decisions that lead to the Iraq War in 2003 ... we are not going to go through it [the report], we are not going to examine it, we are not going to try to make an analysis of it or make judgement of the findings one way or another. Our focus is on the challenges we have in Iraq and Syria right now.
I believe that UK officials are taking it seriously and I am going to let them speak to it ... but that's where our focus is right now, not on doing the forensics on decisions that were made 13 years ago.
