Former US President Donald Trump arrived in New Jersey on Sunday, just hours after shooting in his campaign rally in Butler.

Footage shows the Republican candidate descending the plane, accompanied by armed agents. His right ear, where he was reportedly injured during the shooting, could not be visible, while Trump himself was seen walking in a healthy manner.

Trump was shot to his right ear when he was delivering his speech in the rally in Butler, Pennsylvania on Saturday. As rows of shots fired, the candidate ducked behind his lectern and was surrounded by bodyguards before being taken out of the venue, while raising his fist into the air.

The alleged gunman was killed by the US Secret Service agents. Another attendee was also reported dead in the rally, with two others in critical condition.

Following the incident, President Joe Biden made his statements in a speech in Rehoboth Beach, calling it 'sick' and condemning the violent act, while also saying that he had 'tried to get a hold of Donald.'

Other US politicians like the former president Barack Obama and Secretary of States Antony Blinken also commented on the shooting, condemning political violence and sending wishes to Trump.

The case is currently being investigated as a possible assassination attempt, according to law enforcement officials.
