President Donald Trump‘s pick for labor secretary, Lori Chavez-DeRemer, who could be a candidate for bipartisan support with her previous advocacy for labor unions, could be on more shaky ground now that Democrats are taking their frustrations about Trump’s tactics out on his nominees.

While serving in the House, Chavez-DeRemer cosponsored the PRO Act, which makes it easier for workers to unionize, and Rand Paul (R-KY), a committee member on the Senate’s Health, Education, Labor, and Pensions Committee, already said in January that would not support her.
