Former President Barack Obama will make his first stop on the 2018 campaign trail in Southern California on Saturday, the Democratic Congressional Campaign Committee announced.

Obama will campaign with candidates Josh Harder in the 10th District, T.J. Cox in the 21st District, Katie Hill in the 25th District, Gil Cisneros in the 39th District, Katie Porter in the 45th District, Harley Rouda in the 48th District, and Mike Levin in the 49th.

All seven districts have Republican members of Congress currently holding seats but also voted for Hillary Clinton in 2016.

Reps. Ed Royce of the 39th District and Darrell Issa of the 49th have announced they will retire at the end of their terms.

The former president has so far made only occasional forays into the political realm since leaving office last year.
