Donald Trump said “the world is laughing at us” as he painted a picture of America broken by years of Joe Biden in the White House.

In a victory speech after crushing his rival Nikki Haley in Super Tuesday primaries, Mr Trump attacked his successor’s handling of the economy, crime, and his attempts to secure the southern border.

He told supporters at his Mar-a-Lago resort: “Our cities are being overrun with migrant crime and that’s Biden migrant crime.

“They’ll stand in the middle of the street and have fistfights with police officers...The world is laughing at us. The world is taking advantage of us.”

Mr Trump did not mention Ms Haley once in his speech. But he labelled Mr Biden the “worst president in the history of our country” and claimed that inflation was “destroying the middle class”.

During his time in office, the former president added, there was “no inflation” while the US had “the safest border in the history of our country” thanks to hundreds of miles of wall he claimed to have built.

Mr Trump was denied a clean sweep of Super Tuesday wins when Ms Haley took a narrow victory in Vermont, but otherwise dominated the contest.
