Portman’s net worth rose by more than $1 million last year thanks to several municipal bonds increasing in value.
The senator’s largest assets include an interest in Lebanon House Inc., which has rental commercial property, buildings and vacant land in Kentucky and Ohio, worth at least $1 million. Portman also has a money market savings account worth at least $1 million. He claimed a mineral interest in five acres of land located in Gaines County, Texas, but did not report a value range for the asset.
