A crowd protesting the Trump administration’s immigration policies gathered outside the downtown Washington, D.C., apartment of White House adviser Stephen Miller on Monday night, USA Today reported.

About 20 people marched to Miller's apartment, handing out “wanted” flyers with his face and “missing persons” flyers for the undocumented immigrant children separated from their parents at the border.

The protestors also chanted “immigrants are welcome here” outside Miller’s apartment.

The New York Times reported earlier this month that Miller had pushed for the policy separating immigrant families at the border. Trump signed an executive order last week to end the policy after facing overwhelming criticism.

This isn’t the first time Miller has been publicly targeted over the family separation policy: A protester last week called him a “fascist” at a Mexican restaurant in D.C.

Homeland Security Secretary Kirstjen Nielsen also faced protestors at a different Mexican restaurant in D.C. before ultimately leaving the establishment.
