The former president will be at the Owensboro Convention Center at 3:00 pm, and will make his way to McCracken County High School at 7:00 pm Tuesday evening.
This will be Clinton's third trip to the Bluegrass State to stump for Grimes. In August he spoke at a Lexington fundraiser and a campaign rally in Hazard, the latter providing footage for a statewide TV ad.
Clinton's visit to Owensboro and Paducah comes after Hillary Clinton told thousands of people Wednesday in Louisville to send Grimes to Washington to improve Kentucky's health care reforms under the Affordable Care Act and to raise the minimum wage.
Republican Sen. Mitch McConnell will hold a three-day bus tour through Kentucky's coal country beginning Monday. He has criticized Grimes for appearing with the Clintons, noting their support for Democratic President Barack Obama and his energy policies.
Grimes has said she disagrees with Obama on coal.
