Ben Carson Claims His ‘Sources’ on Syria Are ‘Better’ Than the White House — and Promises to Release the Proof

GREENVILLE, S.C. (TheBlaze/AP) -- Republican presidential candidate Ben Carson is promising to release documents he says will prove his claim that China is involved in Syria's civil war.

The Obama administration and foreign policy experts maintain that there is no evidence for Carson's statement.

Carson says on Friday that he's "surprised my sources are better than theirs." Carson says he would share his documentation with the White House before the weekend is over. He gave no further details.

Carson alleged in Tuesday's GOP debate that Russia, China and "all kinds of factions" are involved in the Syrian war.

National Security Adviser Susan Rice suggested on Thursday that China could have a diplomatic presence, but said she's "not seen any evidence of Chinese military involvement in Syria."

Asked about reports during a White House press briefing on Friday, press secretary Josh Earnest simply said he was "speechless."
