US President Donald Trump drew fresh accusations of racism Monday after he attacked four ethnic-minority Democrats in Congress, telling them to "go back" where they came from.
While Trump denies he is racist, he has a long history of political pandering to white suspicions about other ethnic groups, which many believe helped him win electoral victory in 2016 and which could be important in the election next year.
Well before opened his bid for the White House in 2016, Trump targeted the African-American background of Barack Obama, suggesting the Hawaii-born president was really born outside the United States.
In 2011 he suggested Obama was secretly a Muslim -- another group among his regular targets.
Trump made fighting immigration a key plank of his election platform, and told supporters in speeches that migrants from US neighbour Mexico are "drug smugglers and rapists."
"They're bringing drugs, they're bringing crime, they are rapists, and some, I assume, are good people," he said in a campaign speech.
After becoming president, he defended his border policies in similar terms.
"You wouldn't believe how bad these people are, these aren't people, these are animals," he said of the migrants.
Trump also campaigned on instituting a ban on entries by Muslims, rooted in a long history of attacking Islam.
In 2015 he claimed, falsely, that "thousands and thousands" of Muslims in New Jersey cheered after the 9/11 attacks on New York.
During the 2016 campaign he assailed the parents of Captain Humayun Khan, a Muslim US soldier killed in Iraq, after Khan's father criticized the billionaire White House candidate.
