A top Senate Republican will campaign with GOP candidate Christine O'Donnell in Delaware on Friday.

GOP Conference Chairman Lamar Alexander (Tenn.) will hold a press conference on Friday morning with O'Donnell at a restaurant in Centerville, in one of the most high-profile appearances on behalf of the Delaware candidate.

Republican leaders in the Senate have pledged their support for O'Donnell after she bested centrist GOP Rep. Mike Castle in the Senate primary. But few have campaigned with her in the conservative's uphill race against Democrat Chris Coons.

Republican National Committee Chairman Michael Steele sought to boost O'Donnell's candidacy with an appearance with her on Thursday evening.
