Former Florida Republican Party Chairman Jim Greer pushed back Thursday against state GOP officials, threatening to sue the party to comply with terms of a severance package which officials say was never properly completed.

Greer’s attorney, Damon Chase of Lake Mary, has a seven-page agreement signed by Greer and top party leaders, dated Jan. 4, that would have paid him $11,250 monthly for 11 months. In turn, Greer was to step down as chairman.
