Democratic Presidential Candidate Joe Biden blasts on and gives pressure on the US President Donald Trump to not push a Supreme court nominee before the Presidential election on November 03.

Biden was speaking on Sunday, the day that a second senate Republican voice objections to the Trump’s plan for a quick vote on a replacement to liberal justice Ruth Bader Ginsburg, who died on Friday.

Biden urged Senate Republicans not to vote on any candidate nominated to the Supreme Court as the November election approaches, calling his rival Donald Trump’s plan an “exercise of raw political power.”

Such an appointment by the president, if approved by the Senate, would cement a 6-3 conservative majority that could influence American law and life for decades.

"Voters of this country should be heard ... they're the ones who this Constitution envisions should decide who has the power to make this appointment," Biden, who leads Trump in national opinion polls, said in Philadelphia. "To jam this nomination through the Senate is just an exercise of raw political power."

Biden said that if he wins the November 3 election, he should have the chance to nominate the next Supreme Court justice.

The former vice president rejected the idea of releasing the names of potential nominees, saying that doing so, as Trump did, could improperly influence those candidates' decisions in their current court roles as well as subject them to "unrelenting political attacks."

He reiterated his pledge to nominate an African-American woman to the court, which would be a historic first if he has the opportunity.
