Ben Carson gets buried in ridicule for clueless congressional testimony: 'It's not like this is brain surgery'

Trump Housing and Urban Development Secretary Ben Carson on Tuesday faced tough questioning from House Democrats in which they showed he lacks knowledge of basic concepts related to housing policy.

Rep. Ayanna Pressley (D-MA), for instance, made Carson squirm as he constantly evaded her questions about the importance of safe housing to people's health.

And Rep. Katie Porter (D-CA) confused Carson when she asked him a question about real estate owned properties -- a.k.a., REOs -- that Carson mistook for a question about Oreo cookie sandwiches.

Twitter users instantly piled on to mock Carson for being seemingly clueless about the job he holds -- check out some of the reactions below.
