Mr Blake, who remains in hospital paralysed, said "he was not going to give up" whether he walked again or not, Mr Biden said.

He was speaking at a church meeting in the city where the shooting took place.

President Donald Trump visited Kenosha on Tuesday.

The US leader surveyed areas damaged by the often violent protests that followed the shooting with messages of support for the police.

He did not meet Mr Blake's family, saying it was because they wanted lawyers present.

Wisconsin is an important state in the upcoming presidential election.

Mr Trump narrowly won it in 2016, and for decades the state has backed the eventual winner of the presidency whether Republican or Democrat.

The president has been pushing a campaign message of "law and order". However, Mr Biden has accused Mr Trump of stoking racial division.

Wisconsin's Governor, Tony Evers, said he would "prefer that no-one be here, be it candidate Trump or candidate Biden".

Joe Biden and his wife met Mr Blake's relatives at Milwaukee airport, with Mr Blake on the phone. The meeting was private but Mr Biden and the Blake family lawyer later gave details.
 
Mr Biden said he was struck by the family's "overwhelming sense of resilience and optimism".
