Former Vice President Joe Biden has recorded a web-only ad in support of Steve Dettelbach, the Democratic candidate for Ohio attorney general.

Biden, said to be a front runner for his party's nomination in 2020, says "This November, the future of Ohio is on the ballot; That’s why I’m supporting Steve Dettelbach for Ohio attorney general.

"As a top federal prosecutor, Steve worked with law enforcement to prosecute international drug cartels, crooked CEOs, and human traffickers. He prosecuted corrupt politicians from both parties — Republicans and Democrats. Because Steve believes that nobody is above the law. This election, vote for a prosecutor for Ohio attorney general. Vote Steve Dettelbach. As AG, he’ll have your back."

Dettelbach campaign spokeswoman Liz Doherty didn't disclose how much the campaign was spending on the ad.

She said it will be "on Facebook/Twitter ... part of our substantial online advertising buy."

Biden also issued a fund-raising missive for Dettelbach.

Dettelbach is running against Republican state Auditor Dave Yost.
