Manchester, New Hampshire (CNN) - Three members of the New Hampshire GOP congressional delegation are expected to sign a letter notifying embattled state GOP Chair Jack Kimball they are seeking to remove him from office, according to two Republican sources.
The letter, which has been drafted and is scheduled to be sent out Thursday morning, will be signed by Sen. Kelly Ayotte and Reps. Frank Guinta and Charlie Bass, according to the sources.
National Committeeman Steve Duprey, National Committeewoman Phyllis Woods, and state House Speaker William O'Brien also will sign, according to the sources. The letter notifies Kimball the group is seeking to remove him from office and will call for a vote to do so.
The committee bylaws require Kimball be notified five days before such a vote could occur. A majority of members of the Republican state committee or the executive committee must vote in support of the removal to force him out of office.
Kimball's tenure at the head of the state party has been mired by reports of infighting and disappointing fundraising numbers. After a member of the state party's executive committee called for a special meeting to discuss problems in the party, Kimball pushed the meeting date back to September 1.
His office announced Wednesday evening he will address the media at a press conference Thursday morning. His office did not immediately respond to requests for comment.
The chairmanship is a high-profile position in the first-in-the-nation primary state, which is gearing up for a hotly-contested Republican presidential primary.
