One spectator was killed and two were critically hurt in Saturday's shooting.
Federal authorities are investigating after former President Donald Trump was shot in the ear in an assassination attempt at an election rally in Butler, Pennsylvania, on Saturday.
Blood splattered on Trump's face as Secret Service agents surrounded him and led him off the stage to a waiting vehicle to whisk him away. Trump is "fine," a spokesperson said.
The alleged shooter was killed by snipers. Corey Comperatore, a firefighter and a father of two daughters, died in the shooting Pennsylvania Gov. Josh Shapiro said. Two other people who attended the rally were also injured.
Trump arrives at Newark Liberty International Airport just after midnight early Sunday.
He arrived in Newark about six hours after the shooting took place.
Trump had been scheduled to spend the night at his club in Bedminster prior to the shooting taking place.
The site of the rally in Butler, Pennsylvania is still being considered an active crime scene, law enforcement officials said at a press conference Saturday night.
The FBI said late Saturday that it believes an identification has been made on the suspected shooter, but are not yet released a name "as it is a very sensitive point in the investigation."
"Early indication is that this is a lone wolf," the FBI said in a statement. "But the situation is fluid and the investigators want to be absolutely certain that this person had no support and that no one knew what was coming."
The gunman opened fire with a rifle from the roof of a building about 200 to 300 yards away from the stage where Trump was speaking. A U.S. Secret Service counter-sniper team immediately killed the individual.
Trump left the Butler, Pennsylvania, area just after 11 p.m., according to Gov. Josh Shapiro.
"Under the protection of US Secret Service and with the assistance of the Pennsylvania State Police, former President Trump has now left the Butler area," Shapiro said. "Lori and I are thankful that his team reports that he is fine and we continue to wish him a full and speedy recovery."
The former president left the area about five hours after the shooting took place.
Trump's plane took off from Pittsburgh, but a destination was not released.
