A top Republican group is attacking Senate Democrats over their plan to obstruct President-elect Trump’s Cabinet nominees ahead of the scheduled hearings next week.

America Rising Squared released a web ad on Friday titled “We Owe Deference,” attacking Democrats who are looking to slow down the nominating process by focusing on past statements where the lawmakers called for “deference” toward the president’s administration picks. The video focuses on comments from Sens. Elizabeth Warren, D-Mass., Dianne Feinstein, D-Calif., and Tim Kaine, D-Va.
