“Judge Brett Kavanaugh represents a direct and fundamental threat to that promise of equality and so I will oppose his nomination to the Supreme Court. Specifically, as a replacement for Justice Anthony Kennedy, his nomination presents an existential threat to the health care of hundreds of millions of Americans," Harris, 53, said in a statement just minutes after Trump announced his selection.

Booker, 49, added separately that Kavanaugh should be a "non-starter" for every senator. 
 
“The nomination of Brett Kavanaugh to the Supreme Court is enormously concerning and I’m strongly opposed to it," he said. 
 
Gillibrand, in a series of tweets, said that she would "stand by my pledge to vote no" on Trump's nominee.
 
"The American people deserve the opportunity to make their voices heard in November about this lifetime appointment," Gillibrand, 51, said.
The growing Democratic opposition to Kavanaugh's nomination came after Trump announced him as his choice to succeed retiring Justice Anthony Kennedy.

"We're going to do everything we can to prevent" him from being seated, Sanders, 76, said during the Facebook event. 
 
Contenders for the party's 2020 White House nomination have led the caucus since last year in opposing most of Trump's nominees amid pressure from a resurgent liberal base to play hardball with the administration. 
 
 
 
But Democrats don't have the ability to block Trump's nominee on their own. 
 
After GOP senators got rid of the 60-vote filibuster for Supreme Court nominees last year, a nominee only needs a simple majority, so Republicans could confirm Kavanaugh without help from Democrats if their caucus remains united.
