A former top aide on the House Select Committee on Benghazi has been brought on to advise Republican presidential candidate Ben Carson, in the wake of a series of flubs that prompted questions about Carson's foreign policy expertise.
Last month, the retired neurosurgeon’s campaign quietly hired ex-committee investigator Sara Barrineau, who has also worked in the White House’s Situation Room for the National Security Council and in the State Department, according to LegiStorm, a website that tracks Congress.
The hire came after a series of stumbles for Carson’s compaign, which has seriously damaged his presidential prospects.
Last year, he claimed that China was involved in the ongoing civil war in Syria, which national security officials have laughed off.
Shortly afterwards, an unpaid advisor to Carson told the New York Times that the candidate has been unable to retain “one iota of intelligence information about the Middle East.”
Carson is currently polling around 10 percent nationally, according to a polling average from RealClearPolitics, down from a high of nearly 25 percent in early November.
In addition to Barrineau, Carson’s campaign also hired George Birnbaum, a former advisor to Israeli Prime Minister Benjamin Netanyahu, in the fallout after scrutiny last year.
