Rep. John Patrick Julien said he would challenge the results of the District 107 primary race for the Florida House, which Rep. Barbara Watson won by 13 votes in a recount.
Julien, D-North Miami, was planning to file a court challenge to the results on Friday afternoon.
"I fully expect that we will be filing our official contest today," he said Friday afternoon, adding that the filing would be made within hours.
Julien alleged that absentee ballot fraud and voting irregularities tainted his race, potentially skewing the results in favor of Watson, D-Miami Gardens.
Julien said he did not want to disclose the full details of the challenge before it was filed in court. On Twitter he has said he would try to get at least 14 absentee ballot votes thrown out as fraudulent. His attorney, Juan-Carlos Planas, is also involved in challenging a close Democratic primary Senate race between Reps. Mack Bernard of West Palm Beach and Jeff Clemens of Lake Worth. That race was decided by only 17 votes, and there were potential absentee ballot issues there as well.
Planas is a former Republican legislator from Miami.
