Secretary of Labor nominee Hilda Solis is facing questions on her affiliation with American Rights at Work, a group promoting unions, according to this report.

In the written exchange, Republican senators asked if that would run afoul of Obama’s new ethics policy. Obama has announced that appointees who lobbied on an issue must steer clear of it for their first two years of government service. The president has made some exceptions, however.

In their questionnaire, the senators noted that American Rights at Work has lobbied for passage of the bill. They asked Solis whether she would seek a waiver from the Obama administration or avoid any role in passing the legislation.

Solis replied that she does not need a waiver and has no intention of stepping back. She said she was only a member of Congress exercising her powers.
