Former Vice President Joe Biden will campaign for Democratic Senate candidate Doug Jones in the upcoming special election.

Biden will appear with Jones on Tuesday, Oct. 3 at the Sheraton in Downtown Birmingham. Details about tickets will be released closer to the event.

Biden recorded a robocall endorsing Jones in August in the special election's Democratic primary, which Jones won.

"I have seen Doug Jones' dedication to civil rights and social justice. From his time as U.S. Attorney prosecuting the 16th Street Baptist Church bombers to his private life as an advocate for social justice and economic empowerment, Doug Jones is a proven leader in which we can place our trust. Doug Jones will make a great U.S. Senator," Biden said in a press release.

Jones is a former U.S. Attorney known for prosecuting convicted killers Thomas Blanton and Bobby Frank Cherry for the 1963 Sixteenth Street Baptist Church bombing.

Jones will face either Judge Roy Moore or incumbent Sen. Luther Strange on Dec. 12.
