GOP presidential candidate Ben Carson has canceled a planned trip to Israel and Africa, the candidate said Thursday.
Carson planned to visit Nigeria, Kenya and Zambia at the end of the month. His Israel trip was also supposed to occur before the first caucuses.
Spokeswoman Deana Bass confirmed the two trips were canceled due to "security concerns" Thursday morning, with spokesman Doug Watts adding the campaign made this decision Wednesday afternoon.
"There is significant security concerns," Carson told reporters at an event in Iowa. "It's classified information so I'm just going to say it's too dangerous."
Watts also declined to characterize the threats, but said it was "recommended by the Secret Service based off of briefings they had had."
