SAN ANTONIO -- Texas Secretary of State Carlos Casco, the state official in charge of making sure elections run smoothly, visited San Antonio on Thursday.

He discussed Texas' new voter ID law, Trump's allegations that the elections are rigged, and Wednesday night's debate.

Casco said that he personally has experience with an opponent not conceding victory after an election, in reference to Trump's remarks in Wednesday's debate that he would let Americans know "at the time" whether or not he would accept the result.

"I can tell you that in 2010 my opponent never conceded and after a recount, I won by 69 votes. Is it unusual? You know it's up to the individual," Secretary Casco said.

He also addressed Trump's allegations that the elections are rigged.

"I certainly don't believe it's going to happen in Texas," he said. "There are just too many protocols, there are too many things in place at local offices where the races are counted, so you'd have to have someone very ingenious."
