Joe Biden has made an unbelievable gaffe in his first speech since moving out of the White House. Before he focused his aim on the incumbent President and Elon Musk, Biden used an offensive term for African-Americans as he delivered a speech on social security to crowds in Chicago.

If you were expecting Joe Biden to rally the troops to resist Donald Trump's attacks on the separation of powers and the rule of law, Tuesday’s remarks may be a case of too little too late.

The former US president says his successor has "done so much damage and so much destruction" in his first days in office.
