Joe Biden regrets having pulled out of this year’s presidential race and believes he would have defeated Donald Trump in last month’s election – despite negative poll indications, White House sources have said.

The US president has reportedly also said he made a mistake in choosing Merrick Garland as attorney general – reflecting that Garland, a former US appeals court judge, was slow to prosecute Donald Trump for his role in the 6 January 2021 insurrection while presiding over a justice department that aggressively prosecuted Biden’s son Hunter.

Harris’s ascent to the top of the ticket led to a surge of enthusiasm and improved poll numbers but ultimately ended in a decisive electoral college and popular vote defeat.
