WASHINGTON (REUTERS) - US President Donald Trump has privately blamed 'Antifa people' for storming the US Capitol last Wednesday (Jan 6), even though clear video and documentary evidence exists showing the rioters were overwhelmingly his supporters, Axios reported.

Trump made the remark in a 30-minute-plus phone call Monday morning with House Minority Leader Kevin McCarthy, Axios reported, citing a White House official and another source familiar with the call.

However, Mr McCarthy told Trump in the call, which according to Axios was tense and aggressive at times: "It's not Antifa, it's MAGA. I know. I was there."

Mr McCarthy also advised Mr Trump to call Mr Joe Biden, meet with the president-elect and leave a welcome letter in the Resolute Desk for his successor, according to the report.

The White House did not immediately respond to a request for comment.

A representative of Mr McCarthy was not immediately available for comment.

The storming of the Capitol building last week by Trump supporters delayed the certification of Mr Biden's election victory.

Mr Trump, who has without evidence challenged the validity of Mr Biden's election win, initially praised his supporters but later condemned the violence.

Lawmakers were forced to flee as the building was mobbed by the president's supporters, who overwhelmed security forces.

Five people died in the violence, including one Capitol Police officer who was beaten as he tried to ward off the crowds.
