Manchester Mayor Ted Gatsas is running for governor.
Gatsas launched a campaign page on Facebook making his candidacy official.
WMURreports he's expected to make a formal announcement and file his candidacy paperwork Thursday.
Gatsas was sworn into his fourth term serving as Manchester's mayor in January.
The 65-year-old Gatsas joins Executive Councilor Chris Sununu and State Representative Frank Edelblut of Wilmot as the Republicans seeking to replace outgoing Gov. Maggie Hassan.
Democrats in the race include Executive Councilor Colin Van Ostern and Mark Connolly, the state's former top securities regulator. Former Portsmouth Mayor Steve Marchand says he's also considering a run.
