In the recount of the Nov. 6 election, Scott won by 10,033 votes out of 8.19 million cast statewide, Florida elections officials said on Sunday. Scott took 50.05 percent, compared with 49.93 percent for Nelson, the officials added.

Reports of the uncounted mail-in ballots come as Florida's midterm elections for governor and senator could go to a recount.

Republicans had been counting on votes in the Florida Panhandle, a conservative-leaning region.
