Donald Trump’s pick to lead the Justice Department faced unprecedented criticism from a Senate colleague on Wednesday. New Jersey Democrat Cory Booker told the Senate Judiciary Committee that Alabama Sen. Jeff Sessions is unfit to become the next attorney general.

Sen. Cory Booker: “If confirmed, Senator Sessions will be required to pursue justice for women, but his record indicates that he won’t. He will be expected to defend the equal rights of gay and lesbian and transgender Americans, but his record indicates that he won’t. He will be expected to defend voting rights, but his record indicates that he won’t. He will be expected to defend the rights of immigrants and affirm their human dignity, but the record indicates that he won’t.”

Booker’s testimony was the first time a United States senator has opposed a colleague’s nomination for a presidential Cabinet post. Sen. Booker was joined by civil rights icon, Georgia Congressmember John Lewis, who said Sessions could roll back decades of civil rights gains. Also testifying against Sessions on Wednesday was Amita Swadhin, a survivor of childhood sexual assault. Swadhin cited a 2005 videotape in which Donald Trump is heard boasting of grabbing women by the genitals.

Amita Swadhin: “I live with complex post-traumatic stress disorder and struggle every day to be well. It directly and negatively impacts me when people minimize sexual assault. So to hear Senator Sessions initially say President-elect Trump’s comments do not constitute sexual assault, and then to consider him leading the Department of Justice, has been incredibly worrisome.”

On Tuesday, Sessions revised his earlier statement and said he would consider grabbing a woman by her genitals without consent to be sexual assault. Sessions is expected to sail through a confirmation vote in the full Senate.
