Texas State Comptroller Carole Keeton Strayhorn said Saturday she would challenge Governor Rick Perry in next year's GOP primary.
The 65-year-old Strayhorn made the announcement at a block party just a few streets away from the state capitol.
Strayhorn's announcement came shortly after Perry vetoed education funding from the state budget bill, and called lawmakers back to Austin for a special session on school finance.
Strayhorn has spent the past year attacking Perry's leadership and his failure to bring lawmakers to a consensus on public school funding.
Another possible challenger to Governor Perry says she won't make a run for the top Texas office.
Republican US senator Kay Bailey Hutchison has decided against challenging Governor Rick Perry.
