Former House Speaker Newt Gingrich (R-Ga.) will keynote this fall's Mackinac Republican Leadership Conference in Michigan.

The conference takes place Sept. 23 on Mackinac Island.

"We are excited to have Speaker Newt Gingrich kick off our Conference and address our grassroots leaders on the major issues facing our country," state Party Chairman Bobby Schostak told The Detroit News.

Gingrich also spoke at the Mackinac Policy Conference, hosted by the Detroit Regional Chamber, last June.

Gingrich, who is mulling a White House run, is also set to participate in a New Hampshire state Republican committee speaker series, which will feature a number of possible presidential candidates.
