Donald Trump appeared at the Republican National Convention with a bandage over his ear two days after the assassination attempt.
It was the first time he attended an official event since the assassination attempt.
A crowd of party members greeted him with chants of the word "fight," CNN reports.
He shouted this word at a rally after being wounded in an assassination attempt.
Trump came out to the crowd to the sound of Lee Greenwood's "God Bless the USA."
The assassination attempt on Trump took place at a rally in Pennsylvania on July 13.
The politician was shot by a single gunman from the roof of a building approximately 120 meters from the podium.
As a result of the attack, one spectator was killed and two others were injured.
The attacker was fatally shot by Secret Service agents.
