Former presidential candidate Hillary Clinton implied that the potential confirmation of Brett Kavanaugh to the Supreme Court would bring the United States back to the times of slavery during a speech on Friday.

“I used to worry that they wanted to turn the clock back to the 1950s. Now, I worry they want to turn it back to the 1850s. These will be urgent fights. Stakes could not be higher,” she said during her speech at the American Federation of Teachers.

“This nomination holds out the threat of devastating consequences for workers’ rights, civil rights, LGBT rights, women’s rights, including those to make our own health decisions,” Clinton continued. “It is a blatant attempt by this administration to shift the balance of the Court for decades and to reverse decades of progress.”

President Trump announced Kavanaugh as his nominee to replace Justice Anthony Kennedy last Monday. (RELATED: President Trump’s Supreme Court Pick Is Judge Brett Kavanaugh)

Kavanaugh is widely viewed as a highly qualified candidate, although Democrats are worried what his confirmation would mean overturns of specific rulings like Roe v. Wade.
