DETROIT (AP) — Gov. Rick Snyder says he'll endorse a Republican presidential candidate in the next week.

The first-term GOP governor provided the timetable following a speech Monday to the Detroit Economic Club.

As for who that candidate will be, Snyder responded by saying: "That's still to be determined."

Two of the possible recipients of Snyder's endorsement plan to address the Detroit Economic Club in the days leading up to Michigan's Feb. 28 primary.

Former Pennsylvania Sen. Rick Santorum is to speak at the club's luncheon meeting Thursday. And ex-Massachusetts Gov. Mitt Romney plans to speak to the Economic Club on Feb. 24.

Newt Gingrich and Ron Paul also are in the GOP race.

Michigan and Arizona both host Republican presidential nominating contests on Feb. 28, a week before Super Tuesday.
