Carson, a retired neurosurgeon and conservative author, pointed to what he called President Barack Obama's comfort in lying to the public. He cited the unemployment rate as an example of this.
"I said he reminds you of a psychopath, because they tend to be extremely smooth, charming people who can tell a lie to your face with complete — it looks like sincerity, even though they know it's a lie," Carson told CNBC's John Harwood. "I think he knows full well that the unemployment rate is not 5.5%. He knows that."
(The interview aired before Friday's jobs report, in which the unemployment rate dropped to 5.4%.)
Carson was most likely referring to the debate over how the Bureau of Labor Statistics defines the unemployment rate. Some conservatives have called for more attention to be paid to those who have given up looking for a job, whom the most commonly used statistic excludes.
Carson, repeating an argument he has previously made, said Obama's administration was willing to manipulate the unemployment number to paint a more positive portrait of the economy.
"He knows that people who are not well informed will swallow it hook, line, and sinker — even though they are sitting there in the city and can't find a job," Carson said.
