New Jersey Sen. Cory Booker gave a pep talk in the cramped field office filled with volunteers for Democratic Senate candidate Doug Jones on Sunday in Birmingham with a speech about unity that suggested Roy Moore was a divisive figure without using Moore's name.

"What I know from years of coming down to this great state ... seeing the goodness and the decency of folk, America runs vibrant and real and strong here. The best of who we are is here. This is the United States of America, proud states. Don't let anybody talk about Alabama talk down to Alabama," Booker, who is supporting Jones in Tuesday's special election, told the crowd. "There is goodness and decency and mercy and love here."

In an apparent reference to Moore, Booker said, "We need leaders that are not going to divide us and separate us and tear us up and dissect us," adding that "there are consequential moments in our American history and this is one of them."

Booker also stumped for Jones on Saturday in Montgomery.

He was joined Sunday in Birmingham by Rep. Terri Sewell, D-Birmingham, who has also made other appearances with Jones over the weekend. Sunday's event was held to energize volunteers before they canvassed the city.

"We need you out there knocking on doors handing out literature and telling everyone out there to vote for who?" Sewell said. The crowd responded, "Doug Jones."

Sewell also made references to Moore, whose campaign is battling allegations that he engaged in sexual misconduct, harassment or dated young women in the 1970s when he was an assistant district attorney in Etowah County. Moore has been ahead in most polls during the weekend.

"What's at stake is our very livelihood, right? And we got to vote as if our life depends on it, right? And i think we deserve a senator whose character and integrity and veracity will not be in question on Day One," Sewell said.

Jones also addressed supporters and the media, and called out Moore for not being as active on the campaign trail in the winding days of the campaign.

"What kind of senator hides from his constituencies when he runs for office? What kind of public servant hides and only goes into enclaves and doesn't address the media?" Jones said, referring to Moore. "I'm going to be accessible after this election as I am today."
