Why is Chris Smitherman Lying ?

Because it's just what he does? As the late Dean of Cincinnati used to say, he just makes stuff up. Or maybe it's because he's a sociopath & the boy just can't help himself.
The Business Courier reported that Smitherman was surprised to know his brother, Al, thru Jostin Concrete was engaged in building the Cincinnati Streetcar line but to avoid any conflicts of interest, asked his brother to withdraw from working on the project. Offering no evidence, I guess we should just take his word for it.
But Jostin's involvement goes back to 2009 as reported at UrbanCincy. And the Cincinnati Blog dug up this gem on the NA CP websiteChris Smitherman shouldn't have been re-elected - he should have been impeached.
