Clinton appeared behind the official seal while campaigning with President Obama at an event in Charlotte, N.C., where she ripped into GOP presidential rival Donald TrumpDonald John TrumpSarah Huckabee Sanders becomes Fox News contributor The US-Iranian scuffle over a ship is a sideshow to events in the Gulf South Korea: US, North Korea to resume nuclear talks 'soon' MORE as unserious. 
"Can you imagine him sitting in the Oval Office the next time America faces a crisis?" Clinton asked at the event, her first campaign appearance with Obama.
"The world hangs on every word our president says, and Donald Trump is simply unqualified and temperamentally unfit to be our president and commander in chief," she added. 
Obama took to the lectern after her remarks, leading a chant of "Hillary! Hillary!" before praising his former Democratic presidential rival and secretary of State. 
Obama defended Clinton after Trump earlier in the day accused the FBI of having "bad judgment" by declining to recommend criminal charges against Clinton over her use of a private email server while at State, which FBI director James Comey announced earlier Tuesday.
"I have had a front-row seat to her judgment and her toughness and her commitment to diplomacy," Obama said.
The Democratic pair attempted to portray Trump as a serial tweeter who relies on off-the-cuff remarks.
"Everybody can tweet, but nobody actually knows what it takes to do the job until you've sat behind the desk," Obama said.
The president also took on Trump's "Make America Great Again" campaign slogan. 
"America is really great," Obama said to cheers. "The rest of the world thinks we're pretty darn great. You can look that up. That's a fact."
