Rep. Katherine Harris (R-FL) says she will make a "major announcement" regarding her campaign for Senate in Florida. Harris, who struggled for support throughout the race, has been dogged by questions regarding her involvement with a key figure in the Randy "Duke" Cunningham bribery scandal.

She begged off an appearance at a GOP conference this weekend:

"While there has been much speculation in recent days concerning my campaign, and our party faces challenges in this mid-term election, I am confident with your dedication and commitment, we shall be victorious in November," Harris said.

"Unfortunately, I am unable to join you this weekend, as I prayerfully prepare with my family, friends and advisers to finalize the strategy for a major announcement next week concerning my candidacy for the U.S. Senate."

No time or place has been set for the announcement.
