Donald Trump formally accepted the Republican Party's presidential nomination during a speech capping a convention dominated by the weekend's attempt on his life.
"The discord and division in our society should be healed," the former president said at the start of his speech.
"I am running to be president for all of America, not half of America, because there is no victory in winning for half of America," he added.
Trump's acceptance speech marked the climax and conclusion of the four-day Republican National Convention (RNC) in Milwaukee.
Trump speaks about Biden's 'failed' leadership
Despite adopting a notably conciliatory tone at the start of his speech, but later criticized President Joe Biden's administration.
"Under the current administration, we are a nation in decline," he said.
Going offscript, Trump mentioned Biden by name, something he did not plan to do, according to reports ahead of the speech.
"If you take the ten worst presidents...they would not have done the damage Biden has done," he said.
He also repeated his false claims that the 2020 election was stolen from him, saying, "We're never gonna let that happen again."
"They use Covid to cheat," he said.
Trump vows to end international crisis
Trump also discussed foreign policy, vowing to "end every single international crisis that the current administration has created."
He claimed that if he was president, the war in Ukraine and the Israel-Hamas war would not have happened, but made no mention of how he would stop either.
"I can stop wars with a telephone call," he claimed.
