Sen. Sherrod Brown, D-Ohio, for years claimed an owner-occupancy tax credit at two properties, public records show — a potential violation of the state’s rules governing such incentives.

Brown and his wife, journalist Connie Schultz, also were late paying the tax bill on their Cleveland house at least seven times since purchasing it in 2013, missing a payment deadline as recently as February, according to documents kept by the Cuyahoga County treasurer. At one point in 2015, the county labeled them as delinquent after they failed for months to pay a nearly $1,200 bill.

Responding to questions from NBC News, Brown and Schultz this week paid a $390 penalty stemming from their most recent late payment. Brown also repaid Franklin County, where he owns a condo in Columbus, for occupancy credits he should not have received, his campaign manager, Rachel Petri, said Wednesday. She did not say what caused the errors.

[He’s sorry now and has corrected all these errors, Brown’s office told NBC … now that he’s been caught. Maybe Senate Democrats should pay more attention to their own ethics rather than toss stones at Supreme Court justices over reporting and transparency disputes. — Ed]
