Barack Obama campaigns with Amy Acton, Sherrod Brown in Cleveland

Former President Barack Obama is campaigning with Democratic governor candidate Amy Acton and Democratic U.S. Senate candidate Sherrod Brown on Saturday in Cleveland, Ohio with the midterm elections around the corner.

"Everything is more expensive now," Obama said at the rally. "This administration's actions are directly responsible for rising costs."

Obama argued that Trump made a series of "bad decisions," such as starting the Iran war.

"Iran didn't have nuclear weapons because I had put a deal in place and I didn't have to fire a missile to do it. I just had to engage in diplomacy," he said.
