American actor Dwayne Johnson has expressed regret endorsing Mr Joe Biden for president in the 2020 United States presidential election.

The Hollywood star endorsed Mr Biden in his first contest with Donald Trump four years ago, praising the former vice-president and senator for his “compassion, heart, drive and soul”.

However, in an interview with Fox News on April 5, Johnson, 51, said he would not publicly support the US President in his November rematch with Trump.
