Hinojosa finished 659 votes behind LaMantia. His team paid $17,000 for a recount of votes in Hidalgo, Willacy, and Cameron counties. 

When asked why he only asked for a partial recount, Hinojosa said in part, "Cameron County is paper ballots and we had a lot of mail-in ballots in Hidalgo and those areas; that's why, like we said, would be the most potential for error."

LaMantia's team said a recount is part of the process when the winning margin is so tight.

The recount will start next week.
