President Barack Obama made his first outing on the campaign stump for his former secretary of state just hours after his FBI director blasted her handling of classified material.
The president vigorously vouched for Hillary Clinton's trustworthiness and dedication in his speech in North Carolina on July 5.
"I'm ready to pass the baton," the president declared.
"I'm here today because I believe in Hillary Clinton," he said. "I have had a front-row seat to her judgment and her commitment."
The energetic Obama-Clinton appearance in North Carolina was a show of Democratic unity in a state Clinton is hoping to put back in the party's column. But the moment wasn't what her campaign and the White House imagined during the long primary season.
Shortly before the president and his would-be successor flew to Charlotte together, FBI Director James Comey announced he would not recommend charges against Clinton for her email practices, but only after he presented a searing description of her "extremely careless" handling of classified information that ensured the matter won't be going away.
The White House declined to comment on Comey's findings, saying the investigation was not formally closed and it did not want to appear to be influencing prosecutors.
Still, the timing of the trip pulled the president into a controversy he has at times tried to keep at arm's length. His appearance with Clinton was a reminder that it was his appointee who declined to pursue criminal charges.
Yet Clinton and Obama did not veer from their display of lockstep unity. The duo flew to Charlotte together on Air Force One, and they rode to the rally together in Obama's armored limousine, known as "The Beast." Clinton shared photos of her grandchildren, Charlotte and newborn Aidan, with the president.
Welcomed by a screaming crowd of supporters, the president led chants of "Hillary!" as they stood onstage under banners reading "Stronger Together." He declared that "there has never been any man or woman more qualified for this office than Hillary Clinton, ever. And that's the truth. That's the truth."
Referring back to their own bruising primary battle in 2008, Obama said, "We may have gone toe to toe, from coast to coast, but we stood shoulder to shoulder for the ideals that we share."
Clinton's Republican rival didn't let the Democratic duo's outing go unanswered. As the rally began, Donald Trump released a lengthy statement casting the joint appearance as an example of a "rigged" political system.
"It was no accident that charges were not recommended against Hillary the exact same day as President Obama campaigns with her for the first time," Trump said, later echoing the charges at a rowdy rally held across the state in Raleigh.
Clinton shot back early as she introduced the president, chiding Trump for once leading the questioning of the president's birthplace.
She said Obama was a man that "I was honored to stand with in the good times and the bad times, someone who has never forgotten where he came from. And, Donald, if you're out there tweeting, it's Hawaii."
Obama, too, got in a dig at Trump.
"Anybody can tweet but nobody actually knows what it takes" to be president, he said.
Later, Obama and Clinton dropped in unannounced at Midwood Smokehouse, a barbecue place in Charlotte. He offered a hug to a woman who tried to pay for his meal while Clinton chatted up a woman and her preschool-age child.
At Trump's rally, which attracted a smaller but still enthusiastic crowd, Trump said Obama should be in Washington, dealing with the issues facing the nation, instead of out campaigning.
"We've got a person in the White House that's having a lot of fun," he said. "I watched them today. It's like a carnival act. A lot of fun."
The Clinton campaign hopes Obama can reassure voters about her experience, talent and character — and speak to their questions about her honesty and trustworthiness, some of which stem from the email investigation.
The president cast the negative impressions of her as a result of her many years in the political spotlight. He also noted that he had benefited from Americans' desire for a fresh face.
"Sometimes we take somebody who's been in the trenches and fought the good fight and been steady for granted," Obama said, as Clinton sat behind him. "As a consequence that means sometimes Hillary doesn't get the credit she deserves. But the fact is Hillary is steady and Hillary is true."
