A Republican group is asking Wisconsin state election officials to invalidate the nomination papers of Congresswoman Tammy Baldwin, the AP reported.

The Young Republicans of Dane Country have filed a challenge against Baldwin's nomination paperwork, which they claim is invalid because it lists her campaign office as her address instead of her voting address.

“Tammy Baldwin has always been a blind supporter of liberal interests; However, she is now demonstrating reckless disregard for the voters of the Second Congressional District by not even bothering to conceal the fact that she no longer lives in the District she was elected to represent,” Charla Halverson, president of the GOP group, said in a statement.

“It's obvious her adherence to the Pelosi agenda of unrestrained government spending and destruction of the free market is complete – Baldwin thinks the rules don't apply to her,” she added.

The forty-eight-year-old Democrat became the first openly gay person and the first female representative from Wisconsin to be elected to the House in 1998.

Her first win to Congress was marred by death threats.

Reid Magney, a spokesperson for the Government Accountability Board, said that state election officials have allowed Baldwin to list her campaign office address instead of her voting address for more than a decade because of the threat of violence.

Baldwin is one of three openly gay members of Congress. The other two are Jared Polis of Colorado and Barney Frank of Massachusetts.

Baldwin and her partner of nearly 15 years announced last month they have split.

Officials are expected to take up the issue on Wednesday and Thursday.
