ST. PAUL (AP) -- Republican Paul Gazelka was set to announce his long-expected run for governor on Wednesday.

Gazelka planned a 9 a.m. announcement at the Capitol in St. Paul.

Gazelka, of East Gull Lake, gave up his post as Senate majority leader last week in what was widely seen as a step toward a campaign.

Gazelka joins a growing field of Republicans seeking to knock off Democratic Gov. Tim Walz if Walz, as expected, seeks a second term.

State Sen. Michelle Benson, who leads her chamber's Health and Human Services committee, entered the race last week.

Former legislator Scott Jensen has been in for weeks.
