As House Republicans move one step closer to impeaching Homeland Security Secretary Alejandro Mayorkas, more members of the House GOP conference are skeptical about impeaching his boss.

The House GOP has dedicated a significant portion of its current stint in control of the chamber exploring and hyping up impeaching President Joe Biden, but some within the conference still think the case has yet to be made to the public.

“While I think that it’s pretty clear, I don’t know that the case has been made adequately to the American people,” Rep. Scott Perry (R-PA) said, according to CNN.

The House voted on party lines in December to authorize an impeachment inquiry against Biden, months after proclaiming an inquiry without a vote.
