Former Congressman Tom Tancredo on Monday opened a committee to help Senate President Russell Pearce keep his seat.
The move reinforces the national implications of the special election targeting the Mesa Republican.
Pearce is the first sitting Arizona legislator to officially face a recall.
The new group is called “Committee to Oppose Recall of Russell Pearce.”
Tancredo’s Team America PAC earlier sent out an email soliciting money to help Pearce defend his seat.
The recall election, which is set for Nov. 8, is expected to draw national attention because of the undercurrents surrounding Pearce, who is Arizona’s most visible illegal immigration hawk.
Pearce is the architect of SB1070, Arizona’s tough immigration law passed last year that other states have attempted to copy.
Longtime political observers anticipate that if the conditions were right, the special election could be one of the most expensive in state history.
Pearce’s camp is already gearing up for the battle ahead.
A potential challenger, Jerry Lewis, a Republican from Mesa, is also expected to officially declare his candidacy on Tuesday.
