On Friday, he led by 0.21 percentage point, low enough to require a recount.
"We've all seen the incompetence and irregularities in vote tabulation in Broward and Palm Beach counties for years, but here we go again".
Meanwhile, inside the Broward Supervisor of Elections Office, the canvassing board got back to work hours behind schedule.
Scott has a narrow lead over incumbent Democratic Sen.
"We know in Palm Beach County there are in excess of 10,000 that are going to be reviewed as part of the canvas process because they have stray marks or other write-ins that kept them from being properly scanned and counted", Elias said.
His claim to have won the election was backed by President Trump who tweeted: "Law enforcement is looking into another big corruption scandal having to do with electoral fraud in Broward and Palm Beach".
The news comes as razor-thin margins heighten the possibility of recounts and court battles in the Sunshine State's races for Senate and governor.
"Some believe that this is simply rank incompetence", Scott said.
As every vote counts, more than 1,000 votes in Lee County will not be counted.
The Associated Press has called the governor's race for DeSantis.
"Rick Scott was up by 50,000+ votes on Election Day, now they "found" many votes and he is only up 15,000 votes". Broward's ballot printed vertical instructions, which the guidelines said "cannot share column space with contests - test voters often overlooked races located immediately beneath vertical instructions".
Senator Marco Rubio, another Florida Republican, has also been an outspoken critic of the recount process, tweeting repeatedly about the controversy and earning Mr Trump's praise.
Gaetz, whose district is in Florida's Panhandle, also said the state should take over the Broward elections office. Her department's website said ballots cast on Election Day have been counted.

Mr Kemp now leads at 50.3% to Abrams' 48.7%, according to AP data, but it could take until next week to tally all the votes.
The governors' elections in Florida and Georgia were nearly as close, raising the possibility of a further recount and a possible runoff election respectively.
The results are likewise tightening the gubernatorial race between Democrat Andrew Gillum and Republican Ron DeSantis.
Mr Gillum trails Mr DeSantis now by less than 38,000 votes, which is in recount range if the margin holds. "No ragtag group of liberal activists or lawyers from DC will be allowed to steal this election from the voters in the state of Florida".
