US presumptive Republican presidential nominee Donald Trump takes yet another jab at the government’s refugee policy, saying Syrians accepted for asylum in the country are a "Trojan horse."
Trump was addressing a campaign rally on Saturday at Pittsburgh International Airport near Pittsburgh, Pennsylvania.
A Trojan horse is a mythological wooden statue in which ancient Greeks are said to have concealed themselves in order to enter the city of Troy.
Trump has repeatedly warned that the US should not accept Syrian refugees.
He has also accused US President Barack Obama of purposefully funneling refugees into states with sizeable Republican votes.
Trump, a billionaire businessman from New York, has propelled himself as the presumptive Republican nominee by framing himself as an anti-establishment outsider.
However, his campaign has been defined by controversy from the beginning, including disparaging remarks about women, Mexican immigrants and Muslims.
On Friday, Mitt Romney, the Republican Party's 2012 nominee for US president, warned that if Trump is elected president, he could legitimize racism and bigotry and change the moral fabric of American society.
“I don't want to see a president of the United States saying things which change the character of the generations of Americans that are following,” Romney said. “Presidents have an impact on the nature of our nation, and trickle-down racism, trickle-down bigotry, trickle-down misogyny, all these things are extraordinarily dangerous to the heart and character of America.”
Romney also said that in a race between Democratic presidential candidate Hillary Clinton and Trump, "either choice is destructive."
During Saturday’s rally at Pittsburgh International Airport, Trump revived "Crooked Hillary," his favorite moniker for Clinton, calling her a "maniac." Trump also went after another one of his vocal critics — Senator Elizabeth Warren — calling her "Pocahontas," a reference to her Native American ancestry.
