Housing and Urban Development Secretary Ben Carson wants people to know hes not incompetent at his job hes just a little hard of hearing.

In a Wednesday morning appearance on Fox Business, the Trump appointee sought to recast his abysmal performance at a congressional hearing the previous day, where hed repeatedly struggled to explain basic concepts fundamental to the work he oversees at HUD.

Addressing the already infamous interaction with Rep. Katie Porter (D-Calif.), Carson told Fox that hes very familiar with the terms she used, but that he was having difficulty hearing her.

Carsons excuse doesnt track. Video of the hearing shows him continuing to converse with Porter even as he repeatedly draws blanks throughout her questioning and asks her to explain how things hes in charge of function.

At one point, Porter asks Carson what an REO is. Clearly going blank on the answer, he tries to humorously recast it as an Oreo. (REO stands for real estate owned a term used to describe property that doesnt sell at foreclosure.)

Carson told Fox he had no such lapse. Im very familiar with foreclosed properties and REOs, he said. Ive read extensively about them, knew about them even as a teenager.

In an interview with MSNBC Wednesday afternoon, Porter seemed far from reassured.

Im sorry, but respectfully, I was very clear in my words, the congresswoman said. I was using the term REO and when he couldnt hear me, or I thought he was mishearing me, I took pains to politely correct him to spell out the acronym R-E-O.

I asked him at that point to be sure we were on the same page so that we could have a productive conversation if he knew what an REO was and he gave the incorrect answer, she said.
